That shit winds me up so much; I take ebay way too personally.
In this situation I would block the bidder, delete the message and try to erase the event from my memory!!
I kindly messaged back saying that if they wanted to end the auction early because they didn't want to wait I expected an offer higher than the going price, not lower.
Well done. You can clearly exercise more restraint than I :-)
To be fair, I did respond to a guy once explaining how if I accepted his offer, the fees would pretty much make the sale unviable. After a day or so he came back and bought at the asking price!
