Costco is facing a proposed class-action lawsuit from a shopper who claims the retailer should refund customers for price increases linked to tariffs that the Supreme Court recently ruled unlawful. The suit argues that if Costco receives tariff refunds from the government, it should pass those savings on to customers who paid higher prices. However, it remains unclear whether the government will refund the $166bn in tariff revenue collected, or how such payments would be distributed. Costco says it has not passed all tariff costs on to shoppers and has not committed to direct refunds, instead suggesting any recovered funds could be returned through lower prices and better value for members.
