Can a retailer not accept coupons?

Yes, a retailer can choose not to accept coupons. Acceptance of coupons is typically at the discretion of the retailer, as they set their own policies regarding promotions and discounts. Retailers may opt out of accepting coupons for various reasons, including maintaining profit margins or managing inventory. However, if a retailer advertises that they accept coupons, they are generally expected to honor that commitment.
