Abstract: An improved method for using a calculator tape (12) in a roll (10) and redemption coupons (16) in combination is described. The method uses a novel tape roll (10) for a calculator or cash register (20), including a dried, moisture sensitive, adhesive (13) on one side of the tape which accepts printing from the calculator or cash register and including the coupons (16) provided on the other side (17) of the tape roll opposite the adhesive (13). The coupons can be pasted in a redemption booklet (23) by moistening the adhesive.
