Abstract: A retail coupon document contains two coupons which are hidden from a coupon user, the coupons being for different values. The user selects and pulls one of two intersecting pull strips, thereby revealing one of the coupons and destroying the other, depending upon which pull strip is selected. The pull strips are formed by perforated division lines which are so arranged that a downstream portion of each pull strip passes through one of the coupons. Thus, the revealed (non-destroyed) coupon will possess such downstream perforations. The perforated lines are configured such that each pull strip is less resistant to being pulled off in an upstream portion thereof than in a downstream portion thereof. This ensures that the revealed coupon will not be unduly weakened by the presence of perforations therein.
