Still hanging on to your iPhone 4S? You might have a chance to upgrade for the price of free, you just have to find a Radio Shack.
The retailer is launching a new promotion that cuts $100 off of the $199 iPhone 5S with a two-year contract. This make the smartphone $99, which you can knock off by trading in your iPhone 4S for $100 credit. There you have it: zero dollars. But not quite yet—the catch is you have to be eligible for a new two-year contract with either with Sprint, AT&T or Verizon. For example, if you already have Sprint and want to hop into this promotion, you have to sign on for another two years, or switch to AT&T or Verizon.
The deal starts Friday, and you can get in on it online or in person.
