Costco Wholesale does not accept general manufacturer coupons. Costco has its own coupons and promotional offers, which are distributed to members in the mail and at store locations at various times throughout the year. The primary member of a Business or Goldstar membership, as well as a Business add-on member with a home address on file, will be sent these coupons. These coupons are also generally available at customer service.
Costco coupons are valid only for the dates noted in savings booklets, based on agreements with manufacturers.
