Yesterday, found a space gray iPhone 5s 64GB at my local AT&T Store via online in-store availability at their website. When I was checking out, I was expecting to pay the full retail (device only, off contract) of $850 and no sales tax since I'm located in Portland. The guy helping me tells me it's $740. I ask him if this is the retail price and he tells me that there is a glitch in AT&T systems for all 5s off contract, device only prices. The guy was super friendly, I added the AppleCare+ and helped him get that commission! Might be just Oregon, but worth giving a shot if you're buying the iPhone 5s off-contract! Plenty of space gray and silver models at most AT&T stores. Good luck!
