Walmart offers the refurbished Samsung 55" 4K 2160p WiFi LED-Backlit LCD Ultra HD Smart Television, model no. UN55HU6950F, for $879.99 with free shipping. That's $418 below our May mention of a new model (which was bundled with a $400 Dell Gift card) and the lowest total price we've seen. (It's $269 less than buying a new unit today.) It features a 3840x2160 (2160p) native resolution, WiFi, Internet apps, USB, and four HDMI inputs.
