Do you want an Amazon Fire Phone? If you do, I'll bet you want it at a discount - even with a free year of Amazon's Prime shipping/video/music service, it's a hard sell at two hundred bucks. It's a good thing, then, that the Fire Phone is so often on sale. The latest discount comes courtesy of an eBay seller, who's getting rid of the phones for as little as $140. That includes free shipping and free access to Prime, bringing the effective price down to $40 for a contract-free phone. Not bad.
That $139.99 price is for the 32GB model. You can get the 64GB version for $159.99 at this separate listing - $20 for a 32GB storage bump is not bad at all. These phones are new, not refurbished, and they come with a full warranty and a code to unlock them from AT&T's service. The phone's radio is designed to be used with AT&T LTE, but it will work with any GSM MVNO and with T-Mobile, at least in some locations. Economy shipping to the US is free, but prospective customers from Europe, Canada, Japan, Australia, New Zealand, Costa Rica, and the Dominican Republic can also buy one if they wish.
Of course the biggest drawback to the Fire Phone (which has some pretty respectable hardware) is the Amazon software and lack of integration with Google apps. If this bothers you, there's an unofficial build of CyanogenMod out there waiting for brave tinkerers to turn the Fire Phone into a more conventional Android device. Good luck.
