How many types of Vouchers?

Vouchers can generally be categorized into several types, including gift vouchers, discount vouchers, and promotional vouchers. Gift vouchers are prepaid cards that can be used as a form of payment at specific retailers, while discount vouchers offer a specific percentage or amount off a purchase. Promotional vouchers are often tied to marketing campaigns and can include buy-one-get-one-free offers or limited-time discounts. Each type serves different purposes in consumer transactions and marketing strategies.
