I won the auction. I don't expect to get the machine. Had to have a go. He has previously listed it at $4k.
I only bought it because of the price and don't want it unless it is $300 which I doubt. If there is a price negotiation does anyone want it? If so P.M. me with what you want to pay and I will negotiate on your behalf.
You won the auction which is a binding agreement. I cannot see how the seller can negotiate ?
