Walmart offers the refurbished Samsung 55" 4K Flat HDR LED Smart Television, model number UN55MU800D, for $499.99 plus $19.97 for shipping. That's tied with our mention from three weeks ago as the best deal we've seen and $160 under the lowest price we could find for a new one. It features:
  • 3840x2160 (4K) native resolution
  • HDR Extreme
  • Bluetooth and voice control
  • Smart TV apps
  • 4 HDMI inputs
Note: A 90-day warranty applies, although it's unclear who backs it.
