Costco does not accept manufacturer coupons because they offer their own deals and savings to members through mail and at their locations. The membership fee provides access to wholesale and bulk pricing deals, eliminating the need for coupons. However, there are still ways to save money at Costco, such as considering the Executive membership tier for cash back, shopping with a list, and buying in bulk strategically on items you use frequently.
