A container for transporting and displaying baked products. The container can be stacked in a 0° and 180° stacking configuration, and when in the former, utilizes stacking feet projections to provide additional strength for carrying heavier products, and to substantially prevent lateral motion of the stacked containers. Further, the containers comprise curved stacking feet and stacking receptacles so that when containers are stacked in the 180° stacking configuration, they can be more easily removed. The containers further include substantially non-glossy, non-smooth areas that allow stickers to be more easily removed, and to reduce errors in counting containers by automated counting equipment.
