Its not filmed very well is it? Sometimes we are expected to believe they have driven 300 miles only to come back with maybe 2 items. they probably pick up a van load before returning otherwise it wouldn't be financially viable.
But then again, thinking of the prices Drew charges.....
He says to the sellers, now and again, they have good stuff and he'll be back.
If they see what he can sell their items for, even after taking into account the cost of restoration, I doubt they'd let him through their doors again.
