Not saying the Best Buy leak is fake, but how do they expect to get people to put down a $50 deposit without knowing what their final cost would be? I assume it would be refundable if the price was a lot more than someone expected.
I was told at BB that when you plop down $50 they give you a gift card in it's place so that you just use that when you come back to pay for the phone. If you don't then you are stuck with a $50 gift card.
