Discount coupons are promotional tools that offer customers a reduction in price when purchasing products or services. They can be found in various forms, such as printed paper, digital codes, or mobile app offers. Retailers use these coupons to attract new customers, encourage repeat business, and boost sales during specific promotions or events. Customers can redeem discount coupons at checkout by presenting them to the cashier or entering a code online. These coupons often have expiration dates and specific terms, such as minimum purchase amounts or restrictions on certain items. Popular retailers like Walmart and Target frequently issue discount coupons to enhance customer loyalty.
