Costco sued for seeking refunds on tariffs customers paid

A proposed class-action lawsuit filed in U.S. District Court in Washington accuses Costco of collecting tariff costs from customers through higher prices, then seeking full federal refunds without returning the overcharges to consumers. The complaint alleges the retailer would effectively recover the same tariff payments twice unless a court intervenes. Costco executives made public statements indicating the company raised prices on goods during the tariff period, but the complaint notes the retailer has offered no legally binding commitment to refund customers for the tariff-related markups.
