every time i go to a store, i've never seen any exclusives besides the deluxe optimus at wal-mart. i go on the store's websites, no exclusives come up when i search. no clear space case or jazz or bb or arceee at target, no optimus with comettor at wal-mart. i asked a lady today about the comettor set and she said they never had any transformer two packs. what's going on?
