OK, maybe I'm just a dummy, but why in the world would any seller take an offer from the "dealer".
The premise is this:
You bring your item to a "dealer" (They had 4 in the episode I watched). Let's say you wanted $1,000 for your item (whatever it was). The "dealer" would typically offer you $300 or so. These guys had pawn shops, etc.
If you didn't want to take their "cash money" right then, you could take your chance at an auction. I think the dealers were in one state and the auction might have been in another in some cases.
The parts I watched (while working on my laptop) invariably showed the item bringing more at auction.

When you think about it, why wouldn't they. The dealer has to lowball you so he can sell it and make a profit.
At least at the auction you are going to get closer o what you want, even after commission (which they never mention of course...I guess they think we poor dumb slobs just imagine they do it for free.)

Anyway, I watched it once and I won't watch it again unless one of you can convince me I missed something.
