If you're in the market and don't need the most cutting edge device, Amazon has a solid deal on the LG Optimus G for Sprint. The price for this handset has fallen to a single penny on a 2-year contract. This deal is open to all interested parties, whether it's for a new line of service or not. The Optimus G was previously only this cheap for new customers.
The LG Optimus G came out last fall, but it has since been overshadowed by the likes of the HTC One and Galaxy S4. But hey, there's still plenty to like in the Optimus G.
