Vod has already replied at least a couple of times. It doesn't look like you'll get anything new out of him or change his mind.
So you're saying that it's not ok for the bidder to back out of the deal. But it's ok for the seller to back out of the deal (via shill/self bid). Sounds kinda lopsided. Is there any harm or loss for the seller if the bidder backs out?
He has not answered AFAIK. Give me links to the replies if you feel you're right.
Again, see the difference between a running auction and ended auction.
If I'm the bidder I don't see the difference. You can back out of the deal, why can't I? Is there any harm or loss for the seller if the bidder backs out?
