They rip people off! (Including you!!)
I started watching this show with a laptop in front of me. Every time they buy something I look up how much they sell for on Ebay and man... they're final values are way off!
For example, he valued a vintage vokswagon lunchbox at $150, but they go for 600+ on Ebay... and he payed $80 for it.
There are other examples, but I recommend looking up the prices of the items. I feel like they put the values low cause they don't want people to know they rip them off.
:D
But I love the show.
