[216]*216Justice Scalia
delivered the opinion of the Court.
Section 101(a) of Public Law 86-272, 73 Stat. 555, 15 U. S. C. §381, prohibits a State from taxing the income of a corporation whose only business activities within the State consist of “solicitation of orders” for tangible goods, provided that the orders are sent outside the State for approval and the goods are delivered from out of state. The issue in this case is whether respondent’s activities in Wisconsin fell outside the protection of this provision.

Respondent William Wrigley, Jr., Co., is the world’s largest manufacturer of chewing gum. Based in Chicago, it sells gum nationwide through a marketing system that divides the country into districts, regions, and territories. During the relevant period (1973-1978), the midwestern district included a Milwaukee region, covering most of Wisconsin and [217]*217parts of other States, which was subdivided into several geographic territories.
The district manager for the midwestern district had his residence and company office in Illinois, and visited Wisconsin only six to nine days each year, usually for a sales meeting or to call on a particularly important account. The regional manager of the Milwaukee region resided in Wisconsin, but Wrigley did not provide him with a company office. He had general responsibility for sales activities in the region, and would typically spend 80-to-95% of his time working with the sales representatives in the field or contacting certain “key” accounts. The remainder of his time was devoted to administrative activities, including writing and reviewing company reports, recruiting new sales representatives, making recommendations to the district manager concerning the hiring, firing, and compensation of sales representatives, and evaluating their performance. He would preside at full-day sales strategy meetings for all regional sales representatives once or twice a year. The manager from 1973 to 1976, John Kroyer, generally held these meetings in the “office” he maintained in the basement of his home, whereas his successor, Gary Hecht, usually held them at a hotel or motel. (Kroyer claimed income tax deductions for this office, but Wrigley did not reimburse him for it, though it provided a filing cabinet.) Mr. Kroyer also intervened two or three times a year to help arrange a solution to credit disputes between the Chicago office and important local accounts. Mr. Hecht testified that he never engaged in such activities, although Wrigley’s formal position description for regional sales manager continued to list as one of the assigned duties “[r3epresent[ing]’ the company on credit problems as necessary.”
The sales or “field” representatives in the Milwaukee region, each of whom was assigned his own territory, resided in Wisconsin. They were provided with company cars, but not with offices. They were also furnished a stock of gum [218]*218(with an average wholesale value of about $1,000), a supply of display racks, and promotional literature. These materials were kept at home, except that one salesman, whose apartment was too small, rented storage space at about $25 per month, for which he was reimbursed by Wrigley.
On a typical day, the sales representative would load up the company car with a supply of display racks and several cases of gum, and would visit accounts within his territory. In addition to handing out promotional materials and free samples, and directly requesting orders of Wrigley products, he would engage in a number of other activities which Wrigley asserts were designed to promote sales of its products. He would, for example, provide free display racks to retailers (perhaps several on any given day), and would seek to have these new racks, as well as pre-existing ones, prominently located. The new racks were usually filled from the retailer’s existing stock of Wrigley gum, but it would sometimes happen — perhaps once a month — that the retailer had no Wrigley products on hand and did not want to wait until they could be ordered from the wholesaler. In that event, the rack would be filled from the stock of gum in the salesman’s car. This gum, which would have a retail value of $15 to $20, was not provided without eharge. The representative would issue an “agency stock check” to the retailer, indicating the quantity supplied; he would send a copy of this to the Chicago office or to the wholesaler, and the retailer would ultimately be billed (by the wholesaler) in the proper amount.
When visiting a retail account, Wrigley’s sales representative would also check the retailer’s stock of gum for freshness, and would replace stale gum at no cost to the retailer. This was a regular part of a representative’s duties, and at any given time up to 40% of the stock of gum in his possession would be stale gum that had been removed from retail stores. After accumulating a sufficient amount of stale product, the representative either would ship it back to [219]*219Wrigley’s Chicago office or would dispose of it at a local Wisconsin landfill.
Wrigley did not own or lease real property in Wisconsin, did not operate any manufacturing, training, or warehouse facility, and did not have a telephone listing or bank account. All Wisconsin orders were sent to Chicago for acceptance, and were filled by shipment through common carrier from outside the State. Credit and collection activities were similarly handled by the Chicago office. Although Wrigley engaged in print, radio, and television advertising in Wisconsin, the purchase and placement of that advertising was managed by an independent advertising agency located in Chicago.
Wrigley had never filed tax returns or paid taxes in Wisconsin; indeed, it was not licensed to do business in that State. In 1980, petitioner Wisconsin Department of Revenue concluded that the company’s in-state business activities during the years 1973-1978 had been sufficient to support imposition of a franchise tax, and issued a tax assessment on a percentage of the company’s apportionable income for those years. Wrigley objected to the assessment, maintaining that its Wisconsin activities were limited to “solicitation of orders” within the meaning of 15 U. S. C. § 381, and that it was therefore immune from Wisconsin franchise taxes. After an evidentiary hearing, the Wisconsin Tax Appeals Commission unanimously upheld the imposition of the tax. CCH Wis. Tax Rep. ¶ 202-792 (1986). It later reaffirmed this decision, with one commissioner dissenting, after the County Circuit Court vacated the original order on procedural grounds. CCH Wis. Tax Rep. ¶ 202-926 (1987). The County Circuit Court then reversed on the merits, CCH Wis. Tax Rep. ¶ 203-000 (1988), but that decision was in turn reversed by the Wisconsin Court of Appeals, with one judge dissenting. 153 Wis. 2d 559, 451 N. W. 2d 444 (1989). The Wisconsin Supreme Court, in a unanimous opinion, reversed yet once again, thus finally disallowing the Wisconsin tax. [220]*220160 Wis. 2d 53, 465 N. W. 2d 800 (1991). We granted the State’s petition for certiorari, 502 U. S. 807 (1991).

In Northwestern States Portland Cement Co. v. Minnesota, 358 U. S. 450, 454 (1959), we considered Minnesota’s imposition of a properly apportioned tax on the net income of an Iowa cement corporation whose “activities in Minnesota consisted of a regular and systematic course of solicitation of orders for the sale of its products, each order being subject to acceptance, filling and delivery by it from its plant [in Iowa].” The company’s salesmen, operating out of a three-room office in Minneapolis rented by their employer, solicited purchases by cement dealers and by customers of cement dealers. They also received complaints about goods that had been lost or damaged in shipment, and forwarded these back to Iowa for further instructions. Id., at 454-455. The cement company’s contacts with Minnesota were otherwise very limited; it had no bank account, real property, or warehoused merchandise in the State. We nonetheless rejected Commerce Clause and due process challenges to the tax:
“We conclude that net income from the interstate operations of a foreign corporation may be subjected to state taxation provided the levy is not discriminatory and is properly apportioned to local activities within the taxing State forming sufficient nexus to support the same.” Id., at 452.
The opinion in Northwestern States was handed down in February 1959. Less than a week later, we granted a motion to dismiss (apparently on mootness grounds) the appeal of a Louisiana Supreme Court decision that had rejected due process and Commerce Clause challenges to the imposition of state net-income taxes based on local solicitation of orders that were sent out of state for approval and shipping. Brown-Forman Distillers Corn. v. Collector of Revenue, 234 [221]*221La. 651, 101 So. 2d 70 (1958), appeal dism’d, 359 U. S. 28 (1959). That decision was particularly significant because, unlike the Iowa cement company in Northwestern States, the Kentucky liquor company in Brown-Forman did not lease (or own) any real estate in the taxing State. Rather, its activities were limited to
“the presence of 'missionary men’ who call upon wholesale dealers [in Louisiana] and who, on occasion, accompany the salesmen of these wholesalers to assist them in obtaining a suitable display of appellant’s merchandise at the business establishments of said retailers . . . .” 234 La., at 653-654,101 So. 2d, at 70.
Two months later, we denied certiorari in another Louisiana case upholding the imposition of state tax on the income of an out-of-state corporation that neither leased nor owned real property in Louisiana and whose only activities in that State “consisted] of the regular and systematic solicitation of orders for its product by fifteen salesmen.” International Shoe Co. v. Fontenot, 236 La. 279, 280, 107 So. 2d 640 (1958), cert. denied, 359 U. S. 984 (1959).
Although our refusals to disturb the Louisiana Supreme Court’s decisions in Brown-Forman and International Shoe did not themselves have any legal significance, see Hopfmann v. Connolly, 471 U. S. 459, 460-461 (1985); United States v. Carver, 260 U. S. 482, 490 (1923), our actions in those cases raised concerns that the broad language of Northwestern States might ultimately be read to suggest that a company whose only contacts with a State consisted of sending “drummers” or salesmen into that State could lawfully be subjected to (properly apportioned) income taxation based on the interstate sales those representatives generated. In Heublein, Inc. v. South Carolina Tax Comm’n, 409 U. S. 275 (1972), we reviewed the history of §381 and noted that the complaints of the business community over [222]*222the uncertainty created by these cases were the driving force behind the enactment of §381:
“ ‘Persons engaged in interstate commerce are in doubt as to the amount of local activities within a State that will be regarded as forming a sufficient... eonneetio[n] with the State to support the imposition of a tax on net income from interstate operations and ‘properly apportioned’ to the State.’ ” Id., at 280, n. 5 (quoting S. Eep. No. 658, 86th Cong., 1st Sess., 2-3 (1959)).1
Within months after our actions in these three cases, Congress responded to the concerns that had been expressed by enacting Public Law 86-272, which established what the relevant section heading referred to as a “minimum standard” for imposition of a state net-income tax based on solicitation of interstate sales:
“No State . . . shall have power to impose, for any taxable year..., a net income tax on the income derived within such State by any person from interstate commerce if the only business activities within such State by or on behalf of such person during such taxable year are either, or both, of the following:
“(1) the solicitation of orders by such person, or his representative, in such State for sales of tangible personal property, which orders are sent outside the State for approval or rejection, and, if approved, are filled by shipment or delivery from a point outside the State; and
“(2) the solicitation of orders by such person, or his representative, in such State in the name of or for the [223]*223benefit of a prospective customer of such person, if orders by such customer to such person to enable such customer to fill orders resulting from such solicitation are orders described in paragraph (1).” 73 Stat. 555,15 U. S. C. § 381(a).
Although we have stated that § 381 was “designed to define clearly a lower limit” for the exercise of state taxing power, and that “Congress’ primary goal” was to provide “[c]larity that would remove [the] uncertainty” created by Northwestern States, see Heublein, supra, at 280, experience has proved §381’s “minimum standard” to be somewhat less than entirely clear. The primary sources of confusion, in this case as in others, have been two questions: (1) what is the scope of the crucial term “solicitation of orders”; and (2) whether there is a de minimis exception to the activity (beyond “solicitation of orders”) that forfeits §381 immunity. We address these issues in turn.
A
Section 381(a)(1) confers immunity from state income taxes on any company whose “only business activities” in that State consist of “solicitation of orders” for interstate sales. “Solicitation,” commonly understood, means “[asking” for, or “enticing” to, something, see Black’s Law Dictionary 1393 (6th ed. 1990); Webster’s Third New International Dictionary 2169 (1981) (“solicit”'means “to approach with a request or plea (as in selling or begging)”). We think it evident that in this statute the term includes, not just explicit verbal requests for orders, but also any speech or conduct that implicitly invites an order. Thus, for example, a salesman who extols the virtues of his company’s product to the retailer of a competitive brand is engaged in “solicitation” even if he does not come right out and ask the retailer to buy some. The key question in this case is whether, and to what extent, “solicitation of orders” covers activities that neither explicitly nor implicitly propose a sale.
[224]*224In seeking the answer to that question, we reject the proposition put forward by Wisconsin and its amici that we must construe §381 narrowly because we said in Heublein that “ 'unless Congress conveys its purpose clearly, it will not be deemed to have significantly changed the Federal-State balance,’ ” 409 U. S., at 281-282 (citation omitted). That principle — which we applied in Heublein to reject a suggested inference from §381 that States cannot regulate solicitation in a manner that might cause an out-of-state company to forfeit its tax immunity — has no application in the present case. Because § 381 unquestionably does limit the power of States to tax companies whose only in-state activity is “the solicitation of orders,” our task is simply to ascertain the fair meaning of that term. FMC Corp. v. Holliday, 498 U. S. 52, 57 (1990).
Wisconsin views some courts as having adopted the position that an out-of-state company forfeits its §381 immunity if it engages in “any activity other than requesting the customer to purchase the product.” Brief for Petitioner 21; see also id., at 19, n. 8 (citing Hervey v. AMF Beaird, Inc., 250 Ark. 147, 464 S. W. 2d 557 (1971); Clairol, Inc. v. Kingsley, 109 N. J. Super. 22, 262 A. 2d 213, aff’d, 57 N. J. 199, 270 A. 2d 702 (1970), appeal dism’d, 402 U. S. 902 (1971)).2 Arguably supporting this interpretation is subsection (c) of §381, [225]*225which expands the immunity of subsection (a) when the out-of-state seller does its marketing through independent contractors, to include not only solicitation of orders for sales, but also actual sales, and in addition “the maintenance... of an office ... by one or more independent contractors whose activities ... consist solely of making sales, or soliciting orders for sales . . . .”3 The plain implication of this is that without that separate indulgence the maintenance of an office for the exclusive purpose of conducting the exempted solicitation and sales would have provided a basis for taxation — i e., that the phrase “solicitation of orders” does not embrace the maintenance of an office for the exclusive purpose of soliciting orders. Of course the phrase “solicitation of orders” ought to be accorded a consistent meaning within the section, see Sorenson v. Secretary of Treasury, 475 U. S. 851, 860 (1986), and if it does not embrace maintaining an office for soliciting in subsection (c), it does not do so in subsection (a) either. One might argue that the necessity of special permission for an office establishes that the phrase “solicitation of orders” covers only the actual requests for purchases or, at most, the actions absolutely essential to making those requests.
We think, however, that would be an unreasonable reading of the text. That the statutory phrase uses the term “solicitation” in a more general sense that includes not merely the ultimate act of inviting an order but the entire process associated with the invitation is suggested by the fact that § 381 [226]*226describes “the solicitation of orders” as a sub category, not of in-state acts, but rather of in-state “business activities” — a term that more naturally connotes courses of conduct. See Webster’s Third New International Dictionary 22 (1981) (defining “activity” as “an occupation, pursuit, or recreation in which a person is active — often used in pi. ebusiness activities>”). Moreover, limiting “solicitation of orders” to actual requests for purchases would reduce § 381(a)(1) to a nullity. (It is obviously impossible to make a request without some accompanying action, such as placing a phone call or driving a car to the customer’s location.) And limiting it to acts “essential” for making requests would engender endless uncertainty, contrary to the whole purpose of the statute. (Is it “essential” to use a company car, or to take a taxi, in order to conduct in-person solicitation? For that matter, is it “essential” to solicit in person?) It seems to us evident that “solicitation of orders” embraces request-related activity that is not even, strictly speaking, essential, or else it would not cover salesmen’s driving on the State’s roads, spending the night in the State’s hotels, or displaying within the State samples of their product. We hardly think the statute had in mind only day-trips into the taxing jurisdiction by empty-handed drummers on foot. See United States Tobacco Co. v. Commonwealth, 478 Pa. 125, 140, 386 A. 2d 471, 478 (“Congress could hardly have intended to exempt only walking solicitors”), cert. denied, 439 U. S. 880 (1978). And finally, this extremely narrow interpretation of “solicitation” would cause § 381 to leave virtually unchanged the law that existed before its enactment. Both Brown-Forman (where the salesman assisted wholesalers in obtaining suitable displays for whiskey at retail stores) and International Shoe (where hotel rooms were used to display shoes) would be decided as they were before, upholding the taxation.
At the other extreme, Wrigley urges that we adopt a broad interpretation of “solicitation” which it describes as having been adopted by the Wisconsin Supreme Court based on that [227]*227court’s reading of eases in Pennsylvania and New York, see 160 Wis. 2d, at 82, 465 N. W. 2d, at 811-812 (citing United States Tobacco Co. v. Commonwealth, supra; Gillette Co. v. State Tax Comm’n, 56 App. Div. 2d 475, 393 N. Y. S. 2d 186 (1977), aff’d, 45 N. Y. 2d 846, 382 N. E. 2d 764 (1978)). See also Indiana Dept. of Revenue v. Kimberly-Clark Corp., 275 Ind. 378, 384, 416 N. E. 2d 1264, 1268 (1981). According to Wrigley, this would treat as “solicitation of orders” any activities that are “ordinary and necessary ‘business activities’ accompanying the solicitation process” or are “routinely associated with deploying a sales force to conduct the solicitation, so long as there is no office, plant, warehouse or inventory in the State.” Brief for Respondent 9,19-20; see also J. Hellerstein, State Taxation ¶6.11[2], p. 245 (1983) (“[Solicitation ought to be held to embrace other normal incidents of activities of salesmen” or the “customary functions of sales representatives of out-of-state merchants”). We reject this “routinely-assoeiated-with-solicitation” or “customarily-performed-by-salesmen” approach, since it converts a standard embracing only a particular activity (“solicitation”) into a standard embracing all activities routinely conducted by those who engage in that particular activity (“salesmen”). If, moreover, the approach were to be applied (as respondent apparently intends) on an industry-by-industry basis, it would render the limitations of § 381(a) toothless, permitting “solicitation of orders” to be whatever a particular industry wants its salesmen to do.4
[228]*228In any case, we do not regard respondent’s proposed approach to be an accurate characterization of the Wisconsin Supreme Court’s opinion. The Wisconsin court construed "solicitation of orders” to reach only those activities that are “closely associated” with solicitation, industry practice being only one factor to be considered in judging the “dose[ness]” of the connection between the challenged activity and the actual requests for orders. 160 Wis. 2d, at 82, 465 N. W. 2d, at 811-812. The problem with that standard, it seems to us, is that it merely reformulates rather than answers the crucial question. “What constitutes the ‘solicitation of orders’?” becomes “What is ‘closely related’ to a solicitation request?” This fails to provide the “[cjlarity that would remove uncertainty” which we identified as the primary goal of §381. Heublein, 409 U. S., at 280.
We proceed, therefore, to describe what we think the proper standard to be. Once it is acknowledged, as we have concluded it must be, that “solicitation of orders” covers more than what is strictly essential to making requests for purchases, the next (and perhaps the only other) clear line is the one between those activities that are entirely ancillary to requests for purchases — those that serve no independent [229]*229business function apart from their connection to the soliciting of orders — and those activities that the company would have reason to engage in anyway but chooses to allocate to its in-state sales force.5 Cf. National Tires, Inc. v. Lindley, 68 Ohio App. 2d 71, 78-79, 426 N. E. 2d 793, 798 (1980) (company’s activities went beyond solicitation to “functions more commonly related to maintaining an on-going business”). Providing a car and a stock of free samples to salesmen is part of the “solicitation of orders,” because the only reason to do it is to facilitate requests for purchases. Contrariwise, employing salesmen to repair or service the company’s products is not part of the “solicitation of orders,” since there is good reason to get that done whether or not the company has a sales force. Repair and servicing may help to increase purchases; but it is not ancillary to requesting purchases, and cannot be converted into “solicitation” by merely being assigned to salesmen. See, e. g., Herff Jones Co. v. State Tax Comm’n, 247 Ore. 404, 412, 430 P. 2d 998, 1001-1002 [230]*230(1967) (no §381 immunity for sales representatives' collection activities).6
As we have discussed earlier, the text of the statute (the “office” exception in subsection (c)) requires one exception to this principle: Even if engaged in exclusively to facilitate requests for purchases, the maintenance of an office within the State, by the company or on its behalf, would go beyond the “solicitation of orders.” We would not make any more generalized exception to our immunity standard on the basis of the “office” provision. It seemingly represents a judgment that a company office within a State is such a significant manifestation of company “presence” that, absent a specific exemption, income taxation should always be allowed. Jantzen, Inc. v. District of Columbia, 395 A. 2d 29, 32 (D. C. 1978); see generally Hellerstein, State Taxation ¶ 6.4.
Wisconsin urges us to hold that no postsale activities can be included within the scope, of covered “solicitation.” We decline to do so. Activities that take place after a sale will ordinarily not be entirely ancillary in the sense we have described, see, e. g., Miles Laboratories v. Department of Revenue, 274 Ore. 395, 400, 546 P. 2d 1081, 1083 (1976) (replacing damaged goods), but we are not prepared to say that will invariably be true. Moreover, the presale/postsale distinction is hopelessly unworkable. Even if one disregards the confusion that may exist concerning when a sale takes place, cf. Uniform Commercial Code §2-401,1A U. L. A. 675 (1989), manufacturers and distributors ordinarily have ongoing relationships that involve continuous sales, making it often im[231]*231possible to determine whether a particular incidental activity was related to the sale that preceded it or the sale that followed it.
B
The Wisconsin Supreme Court also held that a company does not necessarily forfeit its tax immunity under §381 by performing some in-state business activities that go beyond “solicitation of orders”; rather, it said, “[c]ourts should also analyze” whether these additional activities were “‘deviations from the norm’” or “de minimis activities.” 160 Wis. 2d, at 82, 465 N. W. 2d, at 811 (citation omitted). Wisconsin asserts that the plain language of the statute bars this recognition of a de minimis exception, because the immunity is limited to situations where “the only business activities within [the] State” are those described, 15 U. S. C. §381 (emphasis added). This ignores the fact that the venerable maxim de minimis non curat lex (“the law cares not for trifles”) is part of the established background of legal principles against which all enactments are adopted, and which all enactments (absent contrary indication) are deemed to accept. See, e. g., Republic of Argentina v. Weltover, Inc., 504 U. S. 607, 618 (1992); Hudson v. McMillian, 503 U. S. 1, 8-9 (1992); Ingraham v. Wright, 430 U. S. 651, 674 (1977); Abbott Laboratories v. Portland Retail Druggists Assn., Inc., 425 U. S. 1, 18 (1976); Industrial Assn. of San Francisco v. United States, 268 U. S. 64, 84 (1925). It would be especially unreasonable to abandon normal application of the de mini-mis principle in construing §381, which operates in such stark, all-or-nothing fashion: A company either has complete net-income tax immunity or it has none at all, even for its solicitation activities. Wisconsin’s reading of the statute renders a company liable for hundreds of thousands of dollars in taxes if one of its salesmen sells a 10-cent item in state. Finally, Wisconsin is wrong in asserting that application of the de minimis principle “excise[s] the word ‘only from the statute.” Brief for Petitioner 27. The word “only” places [232]*232a strict limit upon the categories of activities that are covered by §381, not upon their substantiality. See, e.g., Drackett Prods. Co. v. Conrad, 370 N. W. 2d 723, 726 (N. D. 1985); Kimberly Clark, 275 Ind., at 383-384, 416 N. E. 2d, at 1268.
Whether a particular activity is a de minimis deviation from a prescribed standard must, of course, be determined with reference to the purpose of the standard. Section 381 was designed to increase — beyond what Northwestern States suggested was required by the Constitution — the connection that a company could have with a State before subjecting itself to tax. Accordingly, whether in-state activity other than “solicitation of orders” is sufficiently de minimis to avoid loss of the tax immunity conferred by §381 depends upon whether that activity establishes a nontrivial additional connection with the taxing State.
Ill
Wisconsin asserts that at least six activities performed by Wrigley within its borders went beyond the “solicitation of orders”: the replacement of stale gum by sales representatives; the supplying of gum through “agency stock checks”; the storage of gum, racks, and promotional materials; the rental of space for--’Storage; the regional managers’ recruitment, training, and'evaluation of employees; and the regional managers’ intervention in credit disputes.7 Since none of [233]*233these activities can reasonably be viewed as requests for orders covered by § 381, Wrigley was subject to tax unless they were either ancillary to requesting orders or de minimis.
We conclude that the replacement of stale gum, the supplying of gum through “agency stock checks,” and the storage of gum were not ancillary. As to the first: Wrigley would wish to attend to the replacement of spoiled product whether or not it employed a sales force. Because that activity serves an independent business function quite separate from requesting orders, it does not qualify for §381 immunity. Miles Laboratories, 274 Ore., at 400, 546 P. 2d, at 1083. Although Wrigley argues that gum replacement was a “promotional necessity” designed to ensure continued sales, Brief for Respondent 31, it is not enough that the activity facilitate sales; it must facilitate the requesting of sales, which this did not.8
The provision of gum through “agency stock checks” presents a somewhat more complicated question. It appears from the record that this activity occurred only in connection with the furnishing of display racks to retailers, so that it was arguably ancillary to a form of consumer solicitation. Section 381(a)(2) shields a manufacturer’s “missionary” request that an indirect customer (such as a consumer) place an order, if a successful request wouldigdtimately result in an order’s being filled by a §381 “customer” of the manufac[234]*234turer, i. e., by the wholesaler who fills the orders of the retailer with goods shipped to the wholesaler from out of state. Cf. Gillette, 56 App. Div. 2d, at 482, 393 N. Y. S. 2d, at 191 (“Advice to retailers on the art of displaying goods to the public can hardly be more thoroughly solicitation . . .”). It might seem, therefore, that setting up gum-filled display racks, like Wrigley’s general advertising in Wisconsin, would be immunized by § 381(a)(2). What destroys this analysis, however, is the fact that Wrigley made the retailers pay for the gum, thereby providing a business purpose for supplying the gum quite independent from the purpose of soliciting consumers. Since providing the gum was not entirely ancillary to requesting purchases, it was not within the scope of “solicitation of orders.”9 And because the vast majority of the gum stored by Wrigley in Wisconsin was used in connection with stale gum swaps and agency stock checks, that storage (and the indirect rental of space for that storage) was in no sense ancillary to “solicitation.”
By contrast, Wrigley’s in-state recruitment, training, and evaluation of sales representatives and its use of hotels and homes for sales-related meetings served no purpose apart from their role in facilitating solicitation. The same must be said of the instances in which Wrigley’s regional sales manager contacted Sie Chicago office about “rather nasty” credit disputes involving important accounts in order to “get the account and [Wrigley’s] credit department communicat[235]*235ing.” App. 71, 72. It hardly appears likely that this mediating function between the customer and the central office would have been performed by some other employee — some company ombudsman, so to speak — if the on-location sales staff did not exist. The purpose of the activity, in other words, was to ingratiate the salesman with the customer, thereby facilitating requests for purchases.
Finally, Wrigley argues that the various nonimmune activities, considered singly or together, are de minimis. In particular, Wrigley emphasizes that the gum sales through “agency stock checks” accounted for only 0.00007% of Wrigley’s annual Wisconsin sales, and in absolute terms amounted to only several hundred dollars a year. We need not decide whether any of the nonimmune activities was de minimis in isolation; taken together, they clearly are not. Wrigley’s sales representatives exchanged stale gum, as a matter of regular company policy, on a continuing basis, and Wrigley maintained a stock of gum worth several thousand dollars in the State for this purpose, as well as for the less frequently pursued (but equally unprotected) purpose of selling gum through “agency stock cheeks.” Although the relative magnitude of these activities was not large compared to Wrigley’s other operations in Wisconsin, w$ have little difficulty concluding that they constituted a nontrivial additional connection with the State. Because Wrigley’s business activities within Wisconsin were not limited to those specified in §381, the prohibition on net-income taxation contained in that provision was inapplicable.

Accordingly, the judgment of the Supreme Court of Wisconsin is reversed, and the case is remanded for further proceedings not inconsistent with this opinion.
It is so ordered.
