Ebay impulse buy now seller wants out

yep, if it had been cash on the barrel head, it would be a done deal and no further action.

Unfortunately, for 3rd party transactions, with possession of the title being the proverbial 9/10th of the law, there is pretty much no recourse except negative feedback which can cut both ways.

Stupid them, but they got rewarded!

Flaw of ebay major transaction system relying on integrity of both parties.
