Miсhael Siegel, like many Americans, didn’t like the price he was paying for gasoline. So he sued five of the eight largest oil companies. Siegel moved for class certification, seeking relief under both the Illinois Consumer Fraud and Deceptive Business Practices Act (“ICFA”), 815 111. Comp. Stat. 505/2, and the common law doctrine of unjust enrichment. The district court denied class certification and entered summary judgment for the defendants. We affirm.
I. BACKGROUND
Siegel initiated this consumer class action on behalf of himself and all others similarly situated, asserting that the defendants acted in concert by manipulating refinery margins and capacity to reduce the nation’s supply of gasoline, and that this manipulation caused him to purchase the defendants’ branded gasoline at artificially inflated prices. Siegel testified at his deposition that he purchased gаsoline out of necessity, and that when he needed *934 to make his purchase, he looked to pricing, location, quality, and convenience as factors to consider in deciding where to go, with convenience being the number one factor in his determination. He alsо testified that he continued to purchase the defendants’ gasoline after he believed the defendants were engaging in unfair conduct and that he could (and did) purchase gasoline from non-defendants.
Instead of bringing suit under antitrust law, Siegel brought suit under ICFA, contending the defendants’ purported manipulation of the nation’s supply of gasoline constituted an unfair practice that resulted in artificially inflated prices at the pump. Siegel also sought recovery under the common law theory of unjust enrichment, arguing that the defendants’ intentional restriction of the nation’s supply of gasoline unjustly inflated the price of gasoline throughout Illinois.
After first moving for certification of a nationwide class and multi-state classes or subclasses of retail gasoline purchasers (which the district court denied), Siegel moved for certification of а class comprising only Illinois retail purchasers of gasoline, which the district court also denied. In denying class certification, the district court concluded that Siegel could not establish through common proof that the allegations against the defendants proximately cаused harm to each member of the putative class. This court then denied Siegel’s Fed.R.Civ.P. 23(f) Petition for Leave to Appeal.
Then, the district court granted the defendants’ motion for summary judgment.
Specifically, the district court held that Siegel could not prevail under his unfair practices claim because he failed to set forth sufficient evidence that but for the defendants’ purportedly unfair conduct, he would not have purchased their gasoline. The district court reached its conclusion based on Siegel’s deposition testimony, where he testified that many factors affected his gasoline purchases, including necessity, price, location, quality of gasoline, convenience, and environmental concerns, and that during the relevant time period, he purchased gasoline from non-defendants. Further, Siegel testified that he did not change his gasoline purchasing habits but continued to purchase the defendants’ gasoline even after he believed they were engaging in unfair conduct.
The district court also ruled that Siegel could not prevail on his unjust enrichment claim based on the defendants’ conduct under ICFA, reasoning that because he could not establish a private cause of action under ICFA, unjust enrichment could not serve as the basis for liability.
Finally, the district court entered judgment in favor of the defendants on Siegel’s deceptive practices claim under ICFA, his unjust enrichmеnt claim sounding in quasi-contract, and his civil conspiracy claim. Siegel does not appeal these rulings.
II. DISCUSSION
ICFA “is a regulatory and remedial statute intended to protect consumers, borrowers, and business persons against fraud, unfair methods of competition, and other unfair and dеceptive business practices.”
Robinson v. Toyota Motor Credit Corp.,
*935
A plaintiff is entitled to recovery under ICFA when there is unfair or deceptive conduct.
Robinson,
In addition, to prevail under ICFA, a plaintiff must demonstrate that the defendant’s conduct is the proximate cause of the injury.

A. Class Certification
Siegel appeals the district court’s ruling denying his mоtion for certification of an Illinois consumer class (and its ruling denying his motion for reconsideration). We review the district court’s decision to deny class certification for abuse of discretion.
Payton v. County of Carroll,
A district court may certify a class of plaintiffs if the putative class satisfies all four requirements of Federal Rule of Civil Procedure 23(a) — numerosity, commonality, typicality, and adequacy of representation — and any one of the conditions of Rule 23(b).

Here, Siegel sought certification of “[a]ll purchasers who made retail purchases of any Defendants’ branded gasoline in Illinois during the period from and including December 2, 2000, through and including September 5, 2008.” Without needing to address the Rule 23(a) requirements, the district court denied class certification finding that Siegel failed to demonstrate that common class issues predominated *936 over individuаl issues under Rule 23(b)(3). In reaching this decision, the district court focused on the elements of an ICFA claim and concluded that it would be required to make individual determinations concerning why a plaintiff bought gasoline from a particular supplier (e.g., price, necessity, conveniencе, location, or quality of gasoline) to discern whether the defendants’ conduct proximately caused each plaintiffs injuries. Because of the need for individualized proof of causation, the district court held that common class issues did not predominate.
On appeal, Siegel argues that the defendants’ unfair conduct can readily be proven on a class-wide basis without the need for individual determinations. He asserts that inquiry into the circumstances surrounding each individual class member’s gasoline purchases is not necessary because he can establish proximate cause through the following: “(1) Defendants conspired to artificially raise the retail price of gasoline; (2) Plaintiff and Class members purchased Defendants’ branded gasoline; (3) Plaintiff and Class members had no meaningful opportunity to avoid paying thе higher retail price; and (4) Plaintiff and Class members were damaged by way of paying the higher retail gasoline prices than they would have paid absent Defendants’ conduct.” Pl. Br. at 18. He cites
Windy City Metal Fabricators & Supply, Inc. v. CIT Technology Fin. Services,
Siegel’s arguments are not persuasive. According to Siegel, proof that plaintiffs purchased gasoline during a specified time period is sufficient to prove that they suffered harm based on the defendants’ conduct. Howеver, Siegel cannot establish that the plaintiffs purchased gasoline for the same reason. Indeed, Siegel himself has named a number of factors he considers in determining where to purchase his gasoline. And absent proof as to why a particular plaintiff purchased а particular brand of gasoline, Siegel cannot establish that the defendants’ conduct caused him or her to make that purchase.
See Robinson,
We conclude that the district court did not abuse its discretion in determining that questions of fact commоn to class members did not predominate over any questions affecting only individual members.
B. Unfair Practices and Unjust Enrichment
We now proceed to analyze the district court’s entry of summary judgment against Siegel on his individual ICFA unfair practices claim and unjust enrichment claim sounding in tort. On appeal, Siegel does not contend that the defendants’ conduct was deceptive, does not dispute that the price he paid was clearly advertised at the gasoline station, and does not argue that he had to purchase the defendants’ branded gasoline. But, Siegel maintains that the defendаnts engaged in unfair practices by manipulating gasoline prices and that, as a result of the defendants’ *937 conduct, he paid too much for their gasoline.
Summary judgment is the “put up or shut up” moment in a lawsuit.
Johnson v. Cambridge Indus., Inc.,
We can sympathize with Siegel’s contention that gasoline is expensive. No one likes to pay high рrices for gasoline. Or for any commodity. But absent proof that but for the defendants’ conduct, he would not have purchased the defendants’ gasoline, he is not entitled to relief under ICFA. While it is true that Siegel need not establish all three criteria of unfairness under Robinson to establish his ICFA claim, he must prove causation, i.e., that he was harmed and that the defendants’ conduct caused his harm.
We conclude that Siegel does not satisfy either prong of proximate causation: he fails to show that he was harmed and he fails to demonstrate that the defendants’ conduct caused him harm. Even if Siegel could establish that the defendants’ conduct was unfair, in order to establish harm under
Montes,
Siegel must still show that he suffered substantial injury, and that he could not avoid this injury.
His unjust enrichment claim carries similar shortcomings. To state a cause of action based on a theory of unjust enrichment, a plaintiff must allege that the defendant has unjustly retained a benefit to the plaintiffs detriment, and that defendant’s retention of the benefit violates the fundamental principles of justice, equity, and good conscience.
HPI Health Care Servs., Inc. v. Mt. Vernon Hosp., Inc.,
*938 III. CONCLUSION
For the reasons stated above, the denial of class certification and judgment in favor of the defendants are Affirmed.
