What the fuck? That's made of glued sawdust with contact paper stuck all over it. Such "furniture" is to be assembled once, moved to its intended location, and never again. It's disposable junk. In fact, that kind of shit CAN'T be moved, because torsion on its connectors destroys the sawdust around the socket.
$125 tops, Alex. You got rooked.
$400 was the cheapest for a new large wardrobe closet on the internet. It will last 10 years and that's all that matters.
