Sniper, it isn't in my add, but I told him in a pm. He didn't bitch about it until I listed him as the buyer in the add, and got mad about that. I thought I was doing the guy a good one, "hey, look at the good guy who bought my gear". So he says I'm requiring too much "paperwork" and backs out.

Perhaps I should list in my thread I want a bill of sale. But it is NOT that uncommon a practice, and I'm just covering my own ass.
