A modular display system (10) having first and second nonrectangular vertical support devices (16), a plurality of horizontal support devices (22) configured to couple to the vertical support devices (16), and a plurality of clear molded storage units (12, 14) configured to hold material such that the holding devices (12, 14) are supported by the vertical (16) and horizontal (22) support devices. The plurality of storage units (12, 14) comprises gravity feed bins (12) and scoop bins (14). Also, the vertical support devices (16) include a plurality of upright support members (16A) and the horizontal support devices (22) include a plurality of cross-supports (46, 48) configured to couple to the plurality of upright support members (16A). Finally, there are a plurality of slide supports (58) configured to be coupled to the cross-supports (46, 48) and to extend normally from the cross-supports (46, 48) to slideably engage the scoop bins (14).
