Bust Buy is sending them all back to the stores. Some of the stores have already started receiving them and have also already sold out of them. Some stores have yet to get them, so there is still a chance that a store near you still hasn't gotten their shipment yet.
HPs online store changed today from out of stock to coming soon.
