A new federal class action accuses Costco Wholesale of using discounts and retail price claims that gave shoppers a false picture of how much they were saving, according to a report from USA Herald. The lawsuit, as described in that coverage, centers on the gap between what advertised markdowns suggest and what members actually save at the register. The outlet also points to Federal Trade Commission guidance that warns businesses against manufacturing the look of a bargain by comparing today's price with an inflated or fictitious earlier one.
That is nearly everything that can be confirmed about the new case right now. The USA Herald page could not be opened in full, and searches of the usual court and class-action trackers turned up no complaint, docket number, named plaintiff or filing date for it. Costco's response is also unknown. What follows separates what has been reported about this filing from what is documented in Costco's recent run of pricing litigation, because the context says a lot about where this fight is likely headed.
What the new complaint is said to allege
The reported theory is a familiar one in consumer protection law: a discount is only a discount if the reference point is real. If a retailer advertises a price cut, the shopper reasonably assumes the higher number was a price the item actually sold for. When it was not, the argument goes, the savings are an illusion that nudges people to buy sooner or buy more than they otherwise would.
For a warehouse club, the claim carries extra weight. Costco charges an annual membership fee, and the entire pitch to members is that the fee pays for itself through lower prices. Any suggestion that the savings are overstated cuts at the core of that bargain, which is why pricing suits against the company tend to get attention far beyond the legal pages.
Until the complaint itself surfaces, the specific products, price points, class definition and legal claims remain unverified. Readers should treat the details above as the reported outline of the case, not a settled account.
The yardstick: the FTC's rules on former prices
The federal reference point for this kind of dispute is the FTC's Guides Against Deceptive Pricing, found in Part 233 of Title 16 of the Code of Federal Regulations. The guides date to 1967 and are advisory rather than binding law, but courts and plaintiffs' lawyers lean on them heavily when judging whether a markdown is honest.
The core rule on former-price comparisons is straightforward. A former price is a legitimate basis for advertising a reduction only when it was the actual, bona fide price at which the item was offered to the public on a regular basis for a reasonably substantial period. If the earlier price was never really charged, the guides treat the bargain as a false one. Words such as regularly or formerly do not rescue the claim if the number behind them is not genuine.
The guides also cover comparisons to competitors' prices, manufacturer list prices and similar reference points, which is why a suit over misleading discounts can be built on several different theories at once. Retail class actions of this type have multiplied across the industry, and outlet-style and phantom-markdown cases against other retailers have produced rulings that plaintiffs now cite routinely.
Costco's growing pricing docket
Whatever the outcome of the new case, it lands on top of a crowded docket. Costco has faced a string of suits that, while differing in detail, all ask the same question: do members get the prices they think they are getting?
Online prices that run higher than the warehouse
A 2024 proposed class action, Song v. Costco, filed in the Western District of Washington, alleged that Costco.com listed products at higher prices than the same items cost in warehouses without clearly telling members. One example in the complaint, as reported in coverage of the case, was a 30-roll pack of Charmin Ultra Soft bath tissue bought online for $33.49 when the in-store price was $29.99. A similar online-pricing case was sent back to state court in California in late 2025 after a federal judge granted a plaintiff's motion to remand, and a Quebec firm filed a comparable proposed class action against Costco Canada in December 2024.
The free-shipping case moves forward
A separate Western District of Washington suit, brought by plaintiff Christina Zaimi, alleges Costco led online shoppers to believe they were getting free shipping when the real cost was built into higher product prices. Zaimi says she paid $2,349.99 online for a couch that she claims sells for $2,099.99 in stores. According to Bloomberg Law, in an article dated April 29, 2026, the court denied Costco's motion to dismiss, finding the deception theory plausible and allowing the case to proceed. A ruling at that stage is not a finding that Costco did anything wrong, but it means the company has to defend its pricing practices in discovery.
A $14 million settlement over limited-time emails
The closest cousin to the new suit may be Aaland v. Costco, a Washington state case filed on October 14, 2025. It alleged that Costco sent promotional emails with false or misleading subject lines advertising temporary discounts, under the Washington Commercial Electronic Mail Act and the state Consumer Protection Act. Subject lines cited in the case included a warning that the day was the last to access member-only savings and an offer of hot buys available for five days only. The settlement of $14 million covers Washington residents who received Costco commercial emails between June 2, 2021 and July 7, 2026, with pro rata payments and no proof of purchase required. The court granted preliminary approval on June 23, 2026, the claim deadline was August 24, 2026, and a final approval hearing was set for October 2, 2026. The page describing the settlement does not say whether Costco admits wrongdoing, and one outlet reported a slightly different date for preliminary approval, so details should be checked against the settlement administrator's site.
Tariffs and refunds
A proposed class action in federal court in Seattle takes a different angle: it alleges Costco raised prices to account for tariffs and then sought refunds of those same tariff costs from the government after the tariffs were struck down. The proposed class covers consumers who bought from Costco between February 1, 2025 and February 24, 2026. Costco has asked a judge to dismiss the case, arguing the plaintiff suffered no harm. Other tariff-related suits have been reported in Illinois and Puerto Rico.
How Costco shoppers actually read a price
Costco does not run the kind of constant percentage-off sale that defines department stores and outlet malls, and it leans on its own tag conventions instead. The company does not publish an official decoder, so everything known about those conventions comes from shoppers, bloggers and former employees, and the details vary by warehouse.
The most common reading is that a price ending in .97 signals a markdown, that .00 and .88 endings point to manager markdowns on things such as floor models and damaged boxes, and that an asterisk on the tag means the item will not be restocked once current inventory sells out. Guides disagree on the finer points, with some calling .88 the best price in the building and others treating .97 plus an asterisk as the strongest clearance signal. A .99 ending is generally read as full regular price.
That informality is part of why pricing disputes are hard to resolve. When the meaning of the tag is shopper folklore, a claim that a discount was misleading has to be proven against whatever Costco's actual markdown history shows, and that history lives in records the public cannot see.
What members can do now
For a man trying to make a Costco membership earn its keep, the practical lessons are simple and do not depend on how any of these cases end.
First, compare before buying anything expensive online. The Song and Zaimi cases both involve the same pattern, where a price on the website differs from the price on the warehouse shelf. A quick check of the in-store price, or a call to the warehouse, can erase an online markup of tens or hundreds of dollars.
Second, treat the savings figure on a flyer or email as a claim to test, not a fact. Look at what the item has cost over several visits, and use a price tracker or your own purchase history as the baseline instead of the number in the advertisement.
Third, keep receipts and screenshots of ads on bigger purchases. Plaintiffs in these cases build their claims from exactly that material, and Costco member services is also the first place to ask about a price problem, long before a courtroom enters the picture.
Finally, watch the docket. A complaint filed in federal court is only an allegation, and cases like this commonly take years to resolve, often through settlements that include no admission of wrongdoing. The reported filing will become more meaningful once the complaint is public, when the court, the plaintiffs, the products and the claimed class can be checked against primary documents. Until then, the safest reading is that Costco is again being asked to prove that its famously low prices are as low as they look.
