Read what he typed, guys. He wants to sell it ALL. To let it ALL go. He only wans to sell his ENTIRE inventory.
I don't think we're dealing with a guy looking to sell you this crap piecemeal, otherwise he would have just kept his store open and marked everything as clearance. I think he's looking for someone to drop a good boatload of money and just get the entire wad he has off his hands in one big delivery. Whatever 'cheap' means when you're talking '$400,000' is anybody's guess, but I don't think he's going to let it go for less than the cost of a house.
