Abstract: A method and a system for an increased value of a Coupon are provided. The increased value is achieved by a first number of computing device users who have confirmed the Coupon. A second number of computing device users increases the value of the Coupon to a new value by confirming the Coupon. Confirmation of a Coupon can be achieved by activating a link. Confirmation can also be achieved by sending an e-mail. A first Coupon string contains contacts including a first user of a starting user. The first user becomes a starting user of a next string by activating a new string of contacts. Different coupon strings may achieve different end values of a Coupon. A Coupon may be associated with a special interest. A special interest may be a credit card.
