Walmart offers the Sceptre 49.5" 4K Flat LED Ultra HD Television for $219.99 with free shipping. That's $10 under our mention from three weeks ago, $180 off list, and the lowest price we could find. (For further comparison, we saw it for $20 less on Cyber Monday.) It features a 3840x2160 native resolution, USB, and four HDMI ports.
