I too am seriously considering opening a store. If I understand correctly when you have a store you can list the item in any format, auction, one bid or store inventory. You just can't have the same item in store inventory and say an auction. According to their boards, you don't pay extra on top of your store fee to put items in auction or one-bid. In other words you get gallery and can choose the listing format, with no limit to how many things you sell. If this is the case it is a great deal. The final value fees are also the same for stores as well as for items that are listed without a store. Check out their selling boards, that is where I got this info. Hope this helps.
