Walmart offers the refurbished Vizio 43" 4K 2160p 120Hz WiFi LED-Backlit LCD Ultra HD Smart Television, model no. M43-C1, for $299.99 with free shipping. That's tied with our mention from last May as the lowest total price we've seen. (It's also $90 under the best price we could find for another refurb now.) It features a native resolution of 3840x2160 (2160p), 120Hz refresh rate, full-array LED backlight, 802.11ac dual-band wireless, Internet apps (including Netflix, Hulu, and Pandora), USB, and five HDMI inputs.
