A promotional receipt is a type of receipt given to customers after a purchase, containing coupons on the back for future purchases at the same store. This document may offer a discount on a specific item, a category of products, or even on all items on sale for a particular day. The discounts offered on a promotional receipt may be linked to the purchase of a specific product (called a voucher receipt) or determined based on the customer’s previous purchases. It is important to note that some promotional receipt issuance practices, which encourage the purchase of a specific product to benefit from a promotion on another brand, have been challenged in court.
