If you're tired of the usual Samsung and Nexus deals, perhaps this one will be of interest. Sony's new flagship, the Xperia Z2, is on eBay Daily Deals for the somewhat reasonable price of $599.99 with free shipping in the US.
The Xperia Z2 has a 5.2-inch 1080p LCD and IP58 certified frame for water and dust resistance. Internally, you're looking at specs that can easily stand up to the other 2014 flagship phones including a Snapdragon 801, 3GB of RAM, and a 20.7MP camera. This is the international version of the device, but it has the necessary bands to work on 3G and 4G LTE on AT&T and T-Mobile in the US.
Shipping will cost you a bit if you're not in the US, but it's still a good price. The claimed $799.99 retail price tag isn't entirely accurate, but this is still quite a bit cheaper than most sources for this device, seeing as it's not officially out in the US.
