You get banned for using the AH to grief people . A temporary high price is not griefing people regardless of the price . You can play the game without buying things from the AH . And you can buy any item that can be sold on the AH without ever using the AH . Also there is no way to guarantee that you ' ll be the one buying any of the cheaper supply since everybody can buy those items just as you can . Hell you can ' t even technically corner most markets or have a monopoly on anything since there is no way to remove the supply of an item . There simply is no reason to regulate prices on the AH which in effect Blizzard would be doing by banning people who try to corner markets . <| sep |> After discovering the Explorer 2 on this sub I went to a local high end jewelers to see if they had any in stock . The sales assistant very helpfully said they had one in and would get it for me . 2 minutes later she came back with an apologetic look on her face , apologised and said that it had been sold 5 , yes FIVE , minutes earlier ! Gutted ! !! The search continues !
