Have you checked out ubid.com? I know nothing about its costs, however.
Never heard of Ubid . Perhaps someone will chime in on it's ups and downs.
I wouldn't buy from UBid if it were the last auction site on earth. They allow bids after the auction closes, giving the seller an opportunity to buy their own stuff if the price is unexpectedly low.
When an auction closes it should stay closed. There is a significant cost in one's time to buy through auction rather than retail. If there is no hope of getting a bargain, there's no point in participating. If you can't tell when the last bid has been placed, there's no point in trying.
