I am thinking you meant 64GB model. I see it as $899+$100 gift card. How did you get $800+$100 gift card? Please let me know.
Add to cart and you will see a $100 credit for your next purchase.
NOTE: They are sold out and taking preorders. The 128gb is $900 and this model is $800 + $100 in credit. I would certainly recommend this over the 128gb model (plus they are not taking pre orders for the 128gb model).
Please do not thumb down because this is a pre-order, it would not be very accurate to do so. Many video game pre order deals would never hit front page if thumbing down pre orders made any sense, which it doesn't.
