I got this from another forum:
Man, when I was in the CE business those dudes were super shady. Like Gypsy.
They basically call a manufacturer and say:
"I will buy all your B-Stock, refurbs, Buyer remorse, and obselcent inventory for $30,000 a truck load. We don't give a fuck what's in it. Just fill up a truck with at least X number of palettes."
They already know at a minimum, they will see a 3x return on the money invested on just the items. It doesn't even include what they make at the GATE when they charge $5-10 a head to get in the door.
Then they take it to a Central Warehouse in the middle of America somewhere. Chop it up, and then set-up these 3-day Liquidation Shows.
No warranty is expressed of implied. It's cash and carry and you are on your own.
