An integral, detachable, promotional coupon is formed, at least in part, by a hinged tuck flap extending from an inner major end-closure flap of a carton. The coupon may be confined to the hinged tuck flap or it may extend onto a portion of the inner major flap. The hinged tuck flap may be folded down into the carton in a vertical position, perpendicular to the inner major flap or it may be folded back upon the inner major flap in a horizontal position between the inner and outer major flaps. The top major flap may be glued to the inner major flap without affecting the detachable coupon.
