ZTE's 2015 phone lineup is going to be replaced in the coming months, but you can get them on the cheap right now. The Axon and Axon Pro are both on sale via Amazon for as much as $130 off. They're a little too expensive for what you get normally, but these prices are much more palatable.
The Axon is now selling for $199.98 ($130 off) and the 32GB Axon Pro is $329.98 ($70 off). A 64GB version of the Pro is $349.98 ($100 off). The two phones look very similar, but the specs are very different. The regular Axon has a Snapdragon 801, 2GB of RAM, and a 5.5-inch 1080p screen. The Pro steps up to a Snapdragon 810, 4GB of RAM, and a 5.5-inch 1440p screen. They've both got HiFi sound, a dual lens camera, and 3000mAh battery.
There's no time limit listed on the sale, so you probably have a few days. Although, this might be a permanent price reduction. Either way, a few variants are already showing low stock.
