Costco Member’s Lawsuit Says All Clients Are Owed Tariff Refunds

A Costco Wholesale Corp. member sued the retailer on Wednesday, saying it should reimburse all customers who paid higher prices on its products because of President Donald Trump’s tariffs.

The lawsuit, filed by Costco member Matthew Stockov of Illinois, is one of at least five proposed class action cases identified by Bloomberg News in which a customer has sued a company to seek tariff refunds. EssilorLuxottica SA, the maker of Ray-Ban sunglasses, and FedEx Corp. have also been sued by clients.
