Walmart offers the Vizio D-Series 49.5″ 4K LED-Backlit LCD Ultra HD Smart Television, model no. D50-E1, for $348 with free shipping. That’s $132 under our mention from a month ago (although that included a $125 Dell gift card) and the lowest price we’ve seen. (It’s the best deal now by $50, although most sellers charge around $450.) It features a 3840×2160 (4K) native resolution, full-array LED backlight, 802.11ac wireless, Vizio Internet Apps Plus (Netflix, Hulu Plus, Pandora, etc.), USB, and four HDMI inputs.
