Lumia 635

Update: Looks like the Lumia 635 has sold out on Best Buy's site before the 4 p.m. deadline

Along with one of Microsoft's Surface Pro 3 tablets, Best Buy is running a flash sale on the AT&T GoPhone version of the Lumia 635 for just $19.99. The sale event ends at 4 p.m. Eastern time (1 p.m. Pacific time).

This price is the cheapest we have seen for this 4-5-inch Windows Phone as a stand alone device. There is a current deal where you can get the Lumia 635 for free if you buy a Fitbit Charge band but this is the lowest price we have seen for the phone by itself. Remember, this deal is set to expire in less than an hour so if you are interested, you might want to move now.
