Walmart offers the Sceptre 54.6" 4K LED-Backlit LCD Ultra HD Television for $279.99 with free shipping. That's $20 under last week's mention and the lowest price we've seen; it's even $50 less than the price we saw around Black Friday. (It's a current low by $50.) It features a 3840x2160 (2160p) native resolution, LED backlight, USB, and four HDMI inputs.
