Just been running some auctions for a couple weeks, what Brian says I can agree with, if it's a hot item you should get a lot of bidders. Best one so far for me was the Stefano Ricci shirt that I started at $39. BIN for $99. First bid was $40, next was $50.05 and then a third bidder hit the BIN for $99. I think the draw back of the auction system is the end time, people are going to wait until the last moment to try and get the last bid in. Went to the Barrett-Jackson Car auction and watched them auction off a $4.5 million dollar car, the bidding stays open until no more bids, which is more like the BIN with "Or best offer". I don't know if eBay has that type of format where the bidding will stay open for X amount of time after each bid, but I know it would benefit the sellers. I listed a HSM gold trumpeter blazer for $29 auction BIN $79, ended yesterday no bids, re listed as BIN $29 or best offer and somebody bought it within 5 minutes.
