The first support assembly has at least (a) a first state with no item upon the first support assembly, (b) a second state with at least one item in at least one of the rows and no items in another of the rows and (c) a third state with at least one item in each of the plurality of rows. The system includes a repositioning assembly that is operable to cause an item upon the first support assembly to be shifted from a first position in a first row to a second position in a second row. An item upon the first support assembly is situated to be more accessible to an operator for picking from the first location with the item in the second position than with the item in the first position.
