Same rationale as before:

Buy order has been active since December, and it only went down when the buyer ran out of keys and it went right back up again when he had keys again. If it goes down again check his key stock, going on history it goes right back up when he has keys. I think that strengthens the case because he's willing at any time to spend basically all his keys on the item.
