Hey, guys, I have a question. I returned my S2 at a retail store and preordered the iPhone 4S. Both the devices are the same price. The rep had me slide my card once and I received a receipt that shows a negative -$213.99 (it says change due $0.00), then she proceeds to preorder the iPhone 4S for me, and I swipe again and receive a receipt for a positive $213.99. An hour or so later, I take a look at my bank account and I see that 213.99 was deducted from it. I'm assuming it is a pre-authorization hold or something. My question is, did I get charged an extra 213.99? I thought it was suppose to be just an even swap with the phones.
