Good post and food for thought. I put a knife up for sale a couple of months ago and a well respected member sent me a PM saying he'd take it, but didn't post it in the thread. He also wanted to know if I could hold off for a few days before he sent payment. I said sure, since I had done the exact same thing just a few days prior, and a member here extended that courtesy to me. I made sure when Friday arrived, I sent my payment his way by Priority Mail. But my buyer disappeared. I hear nothing from him, no PMs, emails, nada.
After more than a week of zero communication, I finally sent the guy a PM teling him that if he hadn't sent payment by then (almost ten days after his commitment to buy), to just keep his money and I'd keep my knife. Here again, zero communication, no expalanation or even a sorry ass excuse. Nothing at all. I really wanted to ding the guy, but as has been stated, no deal was consummated and I felt like it would get me nowhere, other than exposing this weasel as someone who is not what he appears to be. Even now, he's yet to communicate with me.
For the sake of fairness I believe your "buyer" should also be exposed, at least to show that he is not a well respected member after all. Why would it be only newer members like Frisky Dingo that get all the heat when they flake?
