While even case ratios would be nice, there really needs to be two case configurations... say each wave is 6 figures. The first configuration would be either a 6 or 12 pack evenly distributed. This gets the variety on the shelf. Each figure is entered in the system as a sparate UPC. Thus as the figures sell, the retailer can order cases of 1 figure, say qty 4 or 6. This way they can get popular figures restocked without having to order figures that would clog the pegs. In this scenario, collectors could order the initial case if they were completists as well.
