Walmart offers the Sceptre 54.6″ 4K LED-Backlit LCD Ultra HD Television, model no. U550CV-U, for $249.99 with free shipping. That’s tied with our mention from ten days ago as the lowest price we’ve seen. (It’s also the second-cheapest new 55″ 4K TV we’ve ever seen and the best deal now by $45.) It features a 3840×2160 (2160p) native resolution, LED backlight, USB, and four HDMI inputs.
