What is a coupon ?

A coupon is a ticket or document that can be exchanged for a financial discount on a product. Customarily, coupons are issued by manufacturers of consumer packaged goods or by retailers, to be used in retail stores as a part of sales promotions. They are often widely distributed through mail, magazines, newspapers and the Internet. Internet coupons have become very popular as of late, because the cost is borne by the user (who has to print off the coupons themselves) as opposed to the businesses issuing the coupons.
