The XL variant of the Microsoft Lumia 950 flagship smartphone is now selling for $565 in the US. Expansys USA has the unlocked, single SIM model listed for that price - the retailer usually sells it for $700. While Expansys is selling both white and black color versions at the discounted rate, the latter is currently out of stock. A quick look on Amazon reveals that the retailer is currently selling the same model (RM-1085) for $590, and has both white and black color options in stock. Meanwhile, Microsoft has the Lumia 950 XL (both colors) listed for $649, although none of them is available for purchase as of now - the listing currently shows 'Email me when available' button instead of 'Buy' or 'Add to cart'.
