A coupon is a small form, for example in a newspaper or magazine, which you send off to ask for information, to order something, or to enter a competition.
What is coupon and how it works?
You cut coupons out of newspapers and magazines, take them to the store and use them to get discounts on certain products. A coupon is the same as cash. For example, if you have a $1.00 off coupon on a box of cereal, the cashier takes the coupon as though it were cash.
