Does size matter? Warehouse clubs such as Costco, BJ’s, and Sam’s Club employ a strategy that includes large product sizes with low per unit costs. Suppose a supplier, such as Clorox, decides to sell super-sized versions of its products to one or more of these clubs, while offering only the smaller, higher perunit-cost items to non-warehouse retail stores. What laws might this supplier practice violate? What types of businesses or individuals might allege injury under this arrangement? How is this practice different from the Toys “R” ?
