davidcyclebackThe auction house is offering the card at a price to the underbidder. The underbidder can chose not to accept the offer.
As non-bidders may have placed bids if the high bid was lower (the high bidder never bid), it's not always true that a lot would have sold for the final bid minus all the high bidder's bids. It's possible it would have sold for the same price if the high bidder never bid. I've not bid as some had placed the bid I wanted to place. If he had not bid, I would have place the same bid.
MastroNet, as they were called, relisted a lot and printed the name of the non-payer in the catalog description.
