Isn't that totally different? I thought brick and mortar stores actually buy inventory (or commit to buy orders in this age of just-in-time) where Amazon is just the middleman connecting buyers and sellers and charging fees on both ends. If Amazon wants to commit to certain sizes of orders, I'm sure the vendors will be happy with contractual price setting.
