A stackable bin includes two spaced apart side walls, each having a front, rear, upper and lower edges; a rear wall having opposite side edges connecting the rear edges of the side walls together, an upper edge and a lower edge; the side walls and the rear wall being slightly inclined inwardly with respect to a vertical plane from the upper edge to the lower edge thereof such that the lower edges of the side walls and the rear wall fit within upper edges of side walls and a rear wall of a second, lower stackable bin; a bottom wall connected to lower portions of the side and rear walls; and a plurality of parallel, spaced apart vertically oriented ribs provided on outer surfaces adjacent the front and rear edges of the side walls, for supporting the stackable bin on the upper edges of the side walls of the second stackable bin, and for increasing structural rigidity of the side walls, at least some of the ribs including a notch in a lower end to receive the upper edges of the side walls of the second stackable bin and an outer interlocking tab at the lower end which engages outer surfaces of the side walls of the second stackable bin when the upper edges of the side walls of the second stackable bin are received in the notches, to hold the side walls of the second stackable bin in alignment and preventing outward movement thereof.
