Did he actually want you to ship the part before he paid? Or was he saying I dont have the money this week I will pay you next week? Because i have done that before. I've never asked anyone to hold a part for me if it sells then sell it to someone else but if its still available I will get it when I get the money. I don't think there is anything wrong with that. Now its different if someone says I will pay you later after you already shipped it or something like that. Just curious.
