Walmart offers the refurbished Vizio 50" 4K 2160p WiFi LED-Backlit LCD Ultra HD Smart Television, model no. D50U-D1, for $429.99 with free shipping. That's the second-best deal we've seen for any 50" 4K 2160p WiFi LED LCD Smart TV, and the lowest outright price we've seen for this particular model. (It's also $168 under the best price we could find for a new one today.) It features a 3840x2160 native resolution (4K), 802.11ac wireless, Smart TV (with access to Netflix, Hulu Plus, Pandora, and other Vizio Internet apps), USB, and five HDMI inputs.
