If you have lots of stuff to list have you looked at the calculator to compare your current fees with opening a store? If you're currently listing with BIN and auction and very few of your auctions have more than one bid then you may be better off listing as BIN at your auction price with a store. With a Basic Store you get 80 free BIN listings per month, 30 day listing exposure and lower FVFs for $20 a month.
