Microsoft Store offers its Microsoft Lumia 640 4G LTE No-Contract Windows Phone 8 for AT&T GoPhone for $29 with free shipping. That's a buck under yesterday's mention (which required in-store pickup) and the lowest total price we've seen. (It's the best deal today by $30, excluding the mentions below.) It features a 5" 1280x720 IPS touchscreen LCD with Corning Gorilla Glass 3, Qualcomm MSM8926 Snapdragon 400 1.2GHz quad-core processor, 1GB RAM, 8GB internal memory, 8-megapixel rear camera, 0.9-megapixel front-facing camera, 1080p video recording at 30fps, Bluetooth 4.0, 4G LTE, 802.11n wireless, microSDXC card slot, and Windows Phone 8.1 OS with Lumia Denim.

Don't mind going to the store? With stock varying by location, Walmart has it for $29.88 and Best Buy for $29.99, both via pickup only.
