Embodiments of various stacking cartons that can be erected from a one-piece blank are provided. In this regard, a representative carton, among others, comprises a bottom wall, side walls and end walls. The side walls are foldably attached to left and right edges of the bottom wall. The end walls are foldably attached to top and bottom side edges of the bottom wall such that the side walls are located between the end walls. Each end wall is foldably attached to an end panel that is designed to fold and engage the inner surface of the end wall. The end wall is foldably attached to first reinforcing side panels at side edges of the end wall. Each first reinforcing side panel is foldably attached to a second reinforcing side panel that is designed to fold and engage the inner surface of the first reinforcing side panel.
