Best Buy offers the Vizio 55" 4K 2160p LED-Backlit LCD Ultra HD Smart Television, model no. D55U-D1, for $379.99 with free shipping. That's $45 under our mention from December of a new unit and the lowest total price we've seen for a new one. (It's also $70 below the best price we could find for a refurbished model today and the second-lowest price we've seen for this TV in any condition.) It features a 3840x2160 resolution, 802.11ac wireless, Internet apps (including Netflix, Hulu Plus, and Amazon Video), USB, and five HDMI inputs.
