Other forms: coupons
A coupon is a slip of paper or a code that cuts the price at the till. Cut out, downloaded, or typed in at checkout.
Newspapers and magazines built circulation on them for decades. British English also says voucher. The digital version is now the norm, and hunting for a discount code before paying is a whole small habit. There is a separate sense in gambling, since a betting coupon is the printed list of fixtures. Extreme couponing is an American pursuit that Britain has never quite taken up.

A coupon is a cut-off piece. French couper means to cut, so the word names the act of detaching it from the sheet rather than anything it is worth.
