I was wondering the same thing. It could have something to do with several bids being placed at the exact same second, possibly one or more of them by an automatic sniping service. I'll be interested in what BeenBurned thinks happened.What everyone else said, or the buyer didn't pay. Maybe she got caught up in the bidding and realized she didn't want to pay that much.
There was something wrong with the bids:
http://www.ebay.com/bfl/viewbids/352062946040?item=352062946040&rt=nc&_trksid=p2047675.l2565
This shouldn't have happened. A person shouldn't have been able to bid $72 or $81 if the price of the item was already over $140.
@BeenBurned Can you explain this?
