Stormville has the cheapest prices, Brimfield has the highest prices, and Elephant's Trunk is in the middles. You see contestants buying an old dresser (not antique, no famous maker, no dovetails) in OK condition for $5 at Stormville, $80 at Brimfield, and $30 at Elephant's Trunk. I get that Brimfield is the largest, but that's incentive to go to Stormville to me if I were junk shopping.
I wonder how many of these vendors also run a junk removal service? I know by me, there's one who gets paid handsomely to remove items, only to sell the good stuff and donate the crap. Not bad to get paid twice.
