Walmart offers the Nokia Lumia 530 3G Windows Phone 8.1 for T-Mobile (no-contract) in White for $39.99. Choose Site-to-Store pickup to dodge the $4.97 shipping fee. (Target and Amazon charge the same price with free shipping.) That's the lowest price we could find by $9 and the best price we've seen since Black Friday weeekend, when we saw it for $5 less. It features a Qualcomm Snapdragon 20 1.2GHz quad-core processor, 4" 854x480 LCD, 512MB RAM, 4GB internal memory, 5-megapixel camera, microSD slot, 3G, WiFi, Bluetooth 4.0, and Microsoft Windows Phone 8.1 OS.
