Like most things in the technology world, if you wait long enough a good deal is bound to be found eventually. Such is the case with the iPhone 5s as starting Friday, RadioShack is reducing their pricing for the latest iPhone down to $99 in-store with a qualifying two-year plan on AT&T, Sprint or Verizon.

If you're still hanging onto an iPhone 4S, the deal is possibly even better. RadioShack will take your iPhone 4s off your hands and give you a $100 credit provided the device is in working order. You can then use that credit purchase an iPhone 5s and ultimately bring the pricing down to free.

RadioShack doesn't note any time frame for the $99 pricing but chances are it won't be an ongoing thing. That said, best to take advantage of it while you can in store starting tomorrow. Anyone going to take RadioShack up on their offer?
