I half collect, half pick. I try to sell the things that I wouldn't normally want to keep around for systems I don't specifically collect for if I can get a good profit. As far as selling things to friends or family, I always give it to them at what I paid or even free if it was cheap enough for me. My brother and I both collect and pick yet we go to the same flea market at the same time looking for the same things. We are basically rivals. He collects gameboy and I collect Saturn and Atari, so we always let each other have at those games before searching through them. Other finds that we get we do like to piss each other off with, but its ok, I'd rather one of us get it than somebody else. Some people make a living off picking so they will be more aggresive about it naturally.
