While Windows 10 Mobile smartphone sales are in full swing, you might want to consider buying an older Windows Phone that can be upgraded to the new OS. This week, the The Microsoft Store has cut the price of the unlocked Lumia 640 XL down to just $199.99.

That's a big $100 price cut, and this one does not appear to be a limited time sale, but a permannt reduction, if the store listing is any indication. The 5.7-inch Lumia 640 XL includes a Qualcomm Snapdragon 400 processor running at 1.2GHz, along with 8GB of storage and 1GB of RAM. It also has a 13MP rear camera, a 5MP front-facing camera and a 3000mAh battery.
