Walmart offers the Sceptre 54.6" 4K 2160p LED-Backlit LCD Ultra HD Television, model no. U550CV-U, for $309.99 with free shipping. That's tied with last week's mention as the lowest price we've seen. (It's the best price we could find now by $72.) It features a 3840x2160 (2160p) native resolution, LED backlight, USB, and four HDMI inputs.
