Walmart offers the Sceptre 42.5" 4K 2160p LED-Backlit LCD Ultra HD Television, model no. U435CV-U, for $279.99 with free shipping. That's the lowest total price we could find by $50, although we saw it for $30 less two weeks ago. It features a 3840x2160 native resolution (four times that of 1080p TVs), LED backlight, USB, and four HDMI inputs.
