Fry's offers the Nokia Lumia 635 No-Contract Windows Phone 8.1 for AT&T Wireless GoPhone for $79.99 with free shipping. That's tied with our mention from two weeks ago as the best deal we've seen for this phone on any prepaid network. (It's the lowest total price we could find today by $19.) It features a Qualcomm Snapdragon 400 1.2GHz quad-core processor, 4.5" 854x480 IPS LCD, 512MB RAM, 8GB internal memory, 5-megapixel camera, microSDHC slot, WiFi, Bluetooth, and Microsoft Windows Phone 8.1 OS.
