A little bit, yes.
More-so, I have had people offer me crap for games. Unless it is something I really want, I decline. One guy in particular from PA has offered me some GI Joe dolls and some robot thing on two separate occasions a year apart. Anytime someone offers you stuff in trade and tells you how much you could make selling it is full of shit. Granted the stuff he was offering was worth some money, it wasn't realistically the value of what I was selling.
Moreso, if it is 'so valuable', why doesn't he sell the stuff and pay me cash while pocketing the difference?? I told him as much the second time. Never heard from him again.
