Visa Wins Costco’s Credit Card Business

Costco announced that its credit card network will be handled by Visa next year, an announcement that comes weeks after it sideswiped Visa rival American Express in a move that ended a 16-year relationship with the retailer. Costco said Citigroup would be the exclusive issuer of the retailer's co-branded credit cards, while Visa will be replacing American Express as the credit card network for Costco in the U.S. and Puerto Rico beginning April 1, 2016.
