I don't understand the business model with these books. Yes you have a commodity item. But is anyone actually spending that much on one of these books? I don't care how rich you are that's financially irresponsible. Seems like the seller is just guaranteeing they have to warehouse the thing for eternity. And that's paying rent for a deadbeat roommate.
Is there an algorithm kicking these numbers out or is it just sheer optimistic greed.
