Sony's Xperia XZs has been on sale in the US since April, and during this time it's seen a few price cuts and deals. While the initial recommended price for it was $699.99, we've also seen it going for $619.99 at one point, and recently its price was cut to $599.99.
Now though you can grab an XZs for cheaper than it's ever been. You do however have to act fast, because only a few units are left in stock at the amazing price of just $545.72. That means you save a whopping $154.27 on the device, but be advised that only the Warm Silver color version is this cheap - the black and blue models both hover around $599.
For the money you get a dual-SIM device with US warranty, which of course comes unlocked. It's compatible with GSM-based carriers only: AT&T, T-Mobile, Straight Talk, MetroPCS, Cricket, Simple Mobile, and Bright Spot for example. Note that it can't be used on CDMA-based networks such as Verizon and Sprint.
Most under performing phones and least popular phones are from Sony, hence the largest price drop.
