New Costco members can now get a $50 Shop Card through Aug. 2

Costco’s latest membership promotion is back through a limited-time collaboration with StackSocial with one of the retailer’s biggest sign-up incentives of the year. Through Aug. 2, eligible new members can receive a $50 Digital Costco Shop Card when they purchase a qualifying annual membership through the promotion, effectively lowering the cost of joining the warehouse club.
