I edited out what I think was wrong with my last post.

Your pawn shop analogy is a good one. If I walked into a pawn shop, and saw a middle aged woman looking at a macbook (Noob, looking at equipmet) that was from 07 running a 1.6 and they were trying to gouge her in price, then yes I would say something. Even if it meant they asked me to leave afterwards.

One of the beautiful things about selling things in an open markteplace, is that sellers are held to a certain level of integrity, and if they aren't holding it up, can be called out on it.
