Walmart offers the Sceptre 54.6″ 4K Flat LED Ultra HD Television, model no. U550CV-U, for $249.99 with free shipping. That’s $150 of list and tied with last week’s mention as the lowest price we’ve seen. (It’s also the second-best price we’ve seen for any new 55″ 4K TV.) It features a 3840×2160 (4K) native resolution, USB 2.0, and four HDMI inputs.
