Carriers will obviously have bigger supply of phones then best buy. I got the 512 direct thru Verizon, but I'm nervous that it will be on back order. With the higher price, Samsung probably produced more 128 versions anticipating a higher demand on them. I ordered at 2:30 on morning of preorder anticipating a back order on the 512's.I saw that as I had to pre-order yesterday. Makes me mad because I kept getting an error trying to add a line on bestbuys site when pre-orders went live. Verizon claimed it was because the phone was on backordered and hadn't released. Knew that was a lie but got off the phone with them. Tried again last night and no issue but now have a delivery date of 8/31 which I'll be out of time. Really hoping that's just a place holder as Verizon still shows release day.
I almost said who cares when I get it and went with the best offering from Sam's club. They have the regular Samsung promotion everyone else has, plus you get a $200 gift card.
