A coupon block refers to a temporary restriction or limitation placed on the use of coupons by a business or retailer. This can occur for various reasons, such as a high volume of coupon redemptions, limited inventory, or a specific time period for the coupon’s validity. During a coupon block, customers may be unable to redeem their coupons or may be limited in the number of coupons they can use per transaction. This can be frustrating for coupon-savvy shoppers, but it is a necessary measure for businesses to manage their promotions effectively. Coupon blocks are typically lifted after the designated time period or when the business deems it appropriate to resume normal coupon usage.
