Walmart offers the refurbished Samsung 54.6" 4K 1080p Curved LED-Backlit LCD HD Smart Television, model no. UN55K6250AFXZA, for $479.99 with free shipping. That's tied with our mention from last week and $270 under the lowest total price we could find for a new one today. It features a 1920x1080 (1080p) native resolution, curved design, WiFi, Bluetooth, Smart Hub apps (including Netflix, YouTube, and Hulu Plus), USB, and three HDMI ports.

A 90-day warranty applies, although it's unclear who backs it.
