If you allready know your way around the AH and you want to speed things up A LOT., then the Quick Auction addon is incredible. It can automate your entire posting and auction canceling once you set things up right. So if you allready try to make money with certain markets i'd definitely suggest you try it out. (aslong as you're not on grim batol! )
