Thе plaintiffs, Jeff Southard, Trish Southard, Jeffrey Stickel, Heather Stickel, Mel Lint, Keith Goodyk, and Greg Dana, filed this class action on September 18, 2003, alleging the defendants, Visa U.S.A. Inc. and MasterCard International Inc., violated Iowa’s competition law, Iowa Code chapter 553 (2003). They also sought relief against the defendants on the common-law ground of unjust enrichment.
The defendants filed a motion to dismiss the pjaintiffs’ аction on the basis that under well-established, common-law principles the plaintiffs could not recover for derivative or remote injuries. The district court granted the defendants’ motion and dismissed the plaintiffs’ petition in its entirety.
The plaintiffs appealed. We affirm.

II. Background Proceedings.
The plaintiffs filed a detailed, forty-eight-page petition. In their pеtition, they allege they are and they represent consumers who purchased goods for cash or used Visa or MasterCard debit cards to make purchases from merchants who accept Visa or MasterCard credit cards as a form of payment. The plaintiffs contend the defendants required merchants who accepted Visa and MasterCard credit cards to also accept Visa and MasterCard debit cards. Due to this tying arrangement, the plaintiffs allege, merchants were forced to pay inflated fees for processing debit transactions over the Visa and MasterCard networks. The plaintiffs assert these magnified costs were passed along to all consumers in the form of higher prices for the goods sold by the merchants.
The plaintiffs allege the tying arrangement orchestrated by the defendants was a violation of Iowa’s competition law. See Iowa Code §§ 553.4, .5. They claim they and others in the class were injured by the defendants’ illegal conduct because all consumers paid merchants artificially inflated prices for all merchandise. See id. § 553.12(2) (“[A] person who is injured ... by conduct prohibited under this chapter may bring suit to ... [r]ecover actual damages resulting from сonduct prohibited under this chapter.”).
The plaintiffs also allege the same conduct of the defendants resulted in the defendants’ unjust enrichment at the expense of the plaintiffs and other class members. The plaintiffs seek restitution of the monies received by the defendants as a result of the defendants’ conduct. 1
The defendants filed a motion to dismiss for failure to state a claim upon which

relief can be granted.
See
Iowa R. Civ. P. 1.421(1). They asserted the plaintiffs could not recover because the plaintiffs’ injuries were derivative and remote.
See Philip Morris Inc.,
The district court granted the defendants’ motion to dismiss. Employing the test set forth in
Associated General Contractors v. California Council of Carpenters,
The district court also rejected the plaintiffs’ claim of unjust enrichment. It concluded the same obstacles to recovery that existed with respect to the plaintiffs’ statutory claim precluded their recovery under an unjust enrichment theory. The court further held that as a result of the merchants’ previous recovery from the defendants for injuries the merchants sustained as a result of the defendants’ illegal tying arrangement, the defendants had been stripped of their ill-gotten gains and no unjust enrichment remained.
See In re Visa Check/MasterMoney Antitrust Litig.,
III. Issues on Appeal.
The plaintiffs claim the district court’s dismissal of their antitrust claims due to the remoteness of their injuries was error. They maintain this court rejected such a limitation when we held in Comes that indirect purchasers could sue under Iowa’s competition law. Thе plaintiffs argue that if we do not find Comes dispositive, we should use the “target area” test to analyze whether they can bring suit under the Iowa competition law, rather than the -Associated General Contractors test employed by the district court.
The plaintiffs also claim the dismissal of their unjust enrichment claim constitutes error. They assert any deficiency in their antitrust claims should not impact the viability of their unjust enrichment theory. The plaintiffs further argue they have sufficiently alleged the required elements for this common-law claim.
IV. Applicability of Comes.
We begin our analysis by addressing the plaintiffs’ assertion that our decision in Comes — that indirect purchasers may bring suit under chapter 553 — is disposi-tive of the present appeal. The premise underlying the plaintiffs’ position is that this court in Comes held common-law rules barring recovery for remote and derivative injuries do not apply to actions brought under chapter 553.
Admittedly, our
Comes
decision contains some expansive statements with respect to the reach of Iowa’s antitrust statute.
See, e.g., Comes,
In
Illinois Brick,
the Supreme Court held that “the overcharged direct purchaser, and not others in the chain of manufacture or distribution, is the party ‘injured in his business or property’ within the meaning of [the federal antitrust law.]”
In
Comes,
this court decided the
Illinois Brick
rule prohibiting indireсt-purchaser suits should not be followed in interpreting Iowa’s competition law.
Thus, with respect to setting the outer limits of what injuries are compensable under Iowa’s competition law, our decision in
Comes
is narrow. We simply rejected the federal rule barring claims by indirect purchasers. We certainly did not, as suggested by the plaintiffs, determine there were
no
limits on who could sue under chapter 553.
Cf. Kanne v. Visa U.S.A Inc.,
Before discussing what limits exist with respect to who may sue under Iowa antitrust law due to the common-law remoteness doctrine, we address the plaintiffs’ argument that they are indirect purchasers in the same position as the
Comes
plaintiffs. The plaintiffs in
Comes
had purchased computers that came with the Windows 98 operating system preinstalled.
Comes,
The plaintiffs bringing suit in
Comes
were indirect purchasers of the Windows 98 operating system because “Microsoft did not directly sell its products [to the plaintiffs, but the plaintiffs] ultimately obtained the products through the stream of commerce.”
Comes v. Microsoft Corp.,
V. Recovery by Person Having a Derivative or Remote Injury.
Iowa law bars recovery of derivative and remote injuries in a variety of situations.
See, e.g., Philip Morris Inc.,
In determining whether this doctrine precludes the plaintiffs’ antitrust claims, we first examine whether recovery for derivative or remote injuries is permitted under Iowa’s competition law. As we noted in
Comes,
the Iowa statute authorizes recovery by a very broad category of persons: “[A] person who is injured ... by conduct рrohibited under this chapter may bring suit to: ... [rjecover actual damages resulting from conduct prohibited under this chapter.”
Obviously, in considering the application of the remoteness doctrine in the present case, we are dealing with the same broad statutory language interpreted in
Comes.
The history of federal antitrust law is, however, quite different with respect to the remoteness doctrine than it was with respect to the indirect-purchaser rule. Prior to the enactment of the Iowa competition law in 1976,
see
1976 Iowa Acts ch. 1224, the United States Supreme Court observed, “The lower courts have been virtually unanimous in concluding that Congress did not intend the antitrust laws to provide a remedy in damages for all injuries that might conceivably be traced to an antitrust violation.”
Hawaii v. Standard Oil Co.,
As we determined in Comes, the interpretation given to the federal antitrust law at the time the Iowa competition law was adopted informs our search for legislative *198 intent. Therefore, we conclude the Iowa legislature did not intend to allow every person tangentially affected by a violation of the statute to have a remedy in damages. This conclusion leads us to consider whether the plaintiffs’ injuries are too remote to be recoverable under chapter 553.
VI. Test to Determine Antitrust Standing.
Although lower courts had unanimously rejected claims for remote injuries prior to Iowa’s adoption of its antitrust law in 1976, the United States Supreme Court did not directly address this issue until its 1983 decision in
Associated General Contractors.
In that case, the Court noted the federal antitrust statute was “broad enough to encompass every harm that can be attributed directly or indirectly to the consequences of an antitrust violation,” but concluded “Congress intended the Act to be сonstrued in the light of its common-law background.”
Associated Gen. Contractors,
The plaintiffs urge us to reject the
Associated General Contractors
(AGC) test and employ the “target area” test to analyze standing. Under the latter test, a plaintiff must simply be in the “target area” of the antitrust conspiracy, that is, “the area of the economy which is endangered by a breakdown of competitive conditions in a particular industry.”
Id.
at 537 n. 33,
The “target area” test, which is in essence an analysis of foreseeability, is inconsistent with Iowa’s common-law limitation on recovery for remote injuries, which is
not
based on the foreseeability of the plaintiffs damages.
See Philip Morris Inc.,
VII. Application of the AGC Test.
To determine standing under our antitrust law, we will examine “the plaintiffs harm, the alleged wrongdoing by the defendants, and the relationship between them.”
Associated Gen. Contractors,
It is not disputed the plaintiffs have alleged a causal connection between the defendants’ illegal conduct and the plaintiffs’ alleged injuries. On the other hand, the plaintiffs are neither consumers of the defendants’ products nor competitors of the defendants. Therefore, the plaintiffs are not “participants in the relevant market,” and their injuries are not of the type sought to be compensated by antitrust laws.
Id.
at 538,
VIII. Unjust Enrichment Claim.
The plaintiffs alleged in their petition that the defendants’ illegal tying arrangements unjustly enriched the defendants at the plaintiffs’ expense because the merchants who paid artificially high prices for the defendants’ debit processing services passed those costs along to the plaintiff consumers. The district court dismissed this claim, concluding it suffered from the same remoteness-of-injury problem as the plaintiffs’ antitrust claims and that there was no enrichment due to the defendants’ settlement of the antitrust action brought by merchants.
Plaintiffs rely on the broad and open-ended nature of the equitable doctrine of unjust enrichment to support their claim.
See State ex rel. Palmer v. Unisys Corp.,
The same conclusion must logically be reached here. Therefore, the district court did not err in dismissing the plain *200 tiffs’ unjust enrichment claim on the basis the plaintiffs’ injuries were too remote.
IX. Summary.
Iowa’s competition law does not provide a remedy to every person who can trace an injury to a defendant’s anticompetitive conduct. Injuries that are remote under the analysis used in the Associated General Contractors case may not be recovered under chapter 553.
In the present case, the plaintiff consumers’ injuries are remote, and therefore, the plaintiffs lack antitrust standing. Moreover, the plaintiffs are not indirect purchasers of the defendants’ services; they are nonpurchasers. Consequently, they cannot benefit from our decision in Comes to allow indirect purchasers to bring suit under Iowa’s competition law.
Finally, the plaintiffs cannot recover under a theory of unjust enrichment because their injuries are too remote.
The district court correctly granted the defendants’ motion to dismiss the plaintiffs’ claims. Accordingly, we affirm.
AFFIRMED.
Notes
. The plaintiffs also allege a claim for "money had and received.” This claim was ultimately dismissed by the district court, who concluded this theory was indistinguishable from the plaintiffs’ unjust enrichment claim. On appeal, the plaintiffs state the district court erred in dismissing their claim for money had and received, but make no argument with respect to this theory and cite no authorities to support this statement distinct from their briefing of the unjust enrichment claim. We therefore do not separately consider or discuss the plaintiffs’ theory of money had and received.
