Costco Wholesale posts its weekly and monthly coupon packages online. To find these coupons, visit Costco.com and type "warehouse coupon offers" into the search bar. The Warehouse Coupons Offer page displays all currently valid coupons, noting which ones can be used online as well.
The coupons listed online are valid at all U.S. Costco stores, though selection may vary depending on location.
Costco also offers a mobile app that allows customers to search for warehouse locations, check location-specific coupons and deals, determine product availability and redeem coupons. Customers with the Costco app can show cashiers their smartphone to redeem coupons with no scanning or printing necessary.
