What's The Deal?!!....

Yeah that's a tough deal but who knows what really happened on his end.
I know I have talked with people about parts for sale, and then forget who after I have deleated pertinant information. I have since started a FABO log on PAPER in a note book so I can keep track better. 8)
Maybe he got more money for it?
Legally for it to be a deal, he would of had to respond back to your reply about the questions asked.
Maybe it was a repop?
I am not defending him, these are just some of my thoughts.
He should have given you first dibs just to be a gentleman.
I would have. I was selling some Dart grills and someone wanted a deal and I was ready to accept. At the last minute someone offered full price. I responded to the first party and gave them the first right of refusal for full price. They refused. Turns out he knows the party who purchased them.
I think all was cool in the end.
