Deal DetailsLast Edited by Shorted July 23, 2016 at 03:19 PM
Best Buy has the iPhone 5S 16GB Space Gray AT&T Version for $199 without any contract. Since it is with AT&T and does not have a commitment attached to it you should be able to get it unlocked off of their website once it arrives.
To order it choose "Add to package" and then choose the "Buy this device without a plan" option at the bottom of the menu.
