Yeah, you add it and buy it and the last step before you charge it to your card it warns you its back ordered until the 7th.
The official release is Monday the 7th so "backordered" is standard language on a site where a gadget hasn't come out yet. I ordered the Note 3 from T-Mo and just got a ship notice it will be delivered on Monday; it was "backordered" or "out of stock" until the 4th (official release date in the U.S.) so it's basically a "pre-order". Point is, its a great discount.
