Walmart offers the refurbished Vizio 50" 4K 2160p WiFi LED-Backlit LCD Ultra HD Smart Television model no. M50-C1, for $399.99 with free shipping. That's $250 under our mention of a new one from two weeks ago, which included a $200 gift card, and the lowest total price we've seen in any condition. (It's $148 under a new one today.) It features a 3840x2160 (2160p) native resolution, Smart TV (with access to Netflix, Hulu Plus, Pandora, and other Vizio Internet apps), USB, and five HDMI inputs.
