When I'm selling I try very hard to avoid conflict and aggravation, etc.
However, it gets old really fast having guys pick up a $100 item than I have marked for $10 and ask if I'll take $1 for it. It gets older faster when it's another table holder that comes over for a $350 engine that I have on sale for $150 and asks if I'll take $100...when he's got 2 of them on his table for $250.
