Gave or used coupons, which are vouchers that provide a discount on products.
From 'coupon,' originally from French 'coupon' meaning 'piece cut off,' derived from Latin 'colpus' (to cut). The term applied to detachable tickets offering discounts.
Digital couponing has replaced paper ones, but the concept goes back to the 1890s when Coca-Cola handed out handwritten tickets for free drinks!
