To use the Costco application for smartphones to redeem in-store coupons, pull up the coupon on your smartphone using the app, and show it to the cashier. However, to redeem some warehouse offers, you must either use the app or have a Costco paper coupon.
Unlike some apps that require you to match in-store paper coupons with the offer listed in the app, the Costco app lets you redeem most in-store coupons by showing the cashier the coupon on your phone. Offers marked with a bold blue arrow require you to redeem them using the app or by presenting the paper coupon. Also, unlike other club stores, Costco doesn’t accept manufacturers’ coupons clipped from other apps or websites and instead accepts only those that it distributes.
Because the Costco app receives regular updates, users always have the most current information about warehouse specials and coupons. While it doesn't list sale prices, Costco’s digital in-store coupons display all of the other information listed on the company’s printed coupons, including the amount of the discount, any purchase limits, product features and conditions.
Redesigned as of July 2015 to be more comprehensive and convenient, the Costco app also helps you locate Costco warehouses, create shopping lists, check and refill prescriptions, upload photos for printing at Costco, and receive sales and other notifications.
