Over a year later, the Nexus 5 remains a great device. I love mine, and I have no desire to move on to the Nexus 6. The phone is increasingly difficult to find these days, so if you want one, listen up. You can currently get a pre-owned 16GB model on StackSocial for $200. This is a significant discount from the gadget's original $349.99.
What may or may not make this deal more compelling is the inclusion of free FreedomPop service. You get one full year of unlimited talk/text and 500MB of LTE a month. The MVNO operates on Sprint's network, so if that's feasible in your area, this offer is looking to save you significantly more than around a hundred bucks. If it isn't, well, this is still a Nexus 5. Do with it what you will. The deal ends in four days.
