Sure you can but will still be paying a $1.50 per auction listing and getting no benifet from having a store unless running BIN listings in there as well, my wife used to sell used clothing auction style, went quite well, encouraged her to go the store format with BIN and sales dropped of dramatically, as BIN take quite some time to gather watchers, so more a long term thing, whereas auctions because of thier low starting price and shorter listing days tend to generate watchers quickly, and some bidding wars just go beyond expectations, where as others get dismall results.
