Walmart must face a class-action lawsuit claiming the multinational retail giant used inaccurate price labels, according to a ruling to a federal appeals court on July 3.

The court order, issued by the 7th U.S. Circuit Court of Appeals in Chicago, opens the door for consumers to prove that the company has violated multiple consumer protection laws.

At the heart of the issue is that the inaccurate prices in Walmart stores constitute a “bait-and-switch” pricing scheme in which purchase prices are higher than those posted on store shelves.

The lawsuit was filed by an Ohio resident named Yoram Kahn. In August, 2022, Kahn purchased multiple items from a Walmart location in Niles, Illinois, and found a 10-15% markup above the listed priced. Kahn’s subsequent lawsuit alleged that similar price discrepancies were found at Walmart locations in Florida, Indiana, Maryland, New Jersey and New York.
