Quoted from LTG:I'd make up two receipts, with game info and serial number. And a big as is, all sales final.
You both sign it, you both get a copy.
Or walk. I tend to go with gut feeling. And no deal is always better than a bad deal.
LTG : )
I'm in agreement. I have signed that type of note as a buyer with no remorse.
No problem walking either. Tell him about the note and signature in advance. He pays and signs or no deal. No hard feelings. If he gives you a bad feeling, no problem walking away. Good luck!
