A voucher in the retail context is a redeemable document or digital code that represents a specific monetary value or discount. Customers can use vouchers to obtain price reductions, discounts, or special offers when making purchases. Retailers issue vouchers as part of promotional campaigns, loyalty programs, or special events to incentivize sales and reward customer loyalty. Vouchers can come in various forms, including physical paper documents, electronic codes, or digital coupons accessible through online platforms. These promotional tools serve to attract customers, encourage repeat business, and enhance the overall value proposition for shoppers.
