Convertible coupon or label

摘要

A convertible coupon is usable as a single primary coupon or as a plurality of secondary coupons that are attachable to selected items. The secondary coupons are separable portions of the primary coupon so use of any of them visibly destroys the integrity of the primary coupon to prevent fraud. Several preferred embodiments show various applications and ways of attaching the primary and secondary coupons to one another and to products.
