Expansys is currently offering some sweet savings on both the Nexus 5 and Nexus 6, with prices as low as $180. On the Nexus 5, Expansys has both new and refurbished units in stock, in both 16 and 32GB storage capacity and your choice of red, white or black. While the smartphone is two years old at this point, if you want to get your hands on the latest version of stock Android, it is still worth the money.
Last year's Nexus 6 is also available at a discounted price, coming in at $310 for a brand new 32GB version. It's currently available in both white and black, though they don't appear to have a 64GB variant on sale currently.
