shillers love second-chancing it
in a real life auction, if a winning bidder fails to pay, you get offered the #lot at the price at which your final bid was before you went head-to-head with the timewaster i.e. an item is at £10, you bid £12, waster bids £14 and it keeps going up to, say £20 with waster as winning bidder. Waster pulls out. Item is offered to you at £12.
