Walmart offers the Seiki 69.5" 4K Flat LED Ultra HD Smart Television, model no. SC-70UK850N, for $559.99. Choose in-store pickup to dodge the $49.97 shipping fee. That's $440 off list and the lowest price we could find, although we saw this for $10 less ten days ago. It features a 3840x2160 (4K) native resolution, Smart TV apps (including Netflix, YouTube, Vudu, more), two USB ports, and three HDMI inputs.
You don't need to hire a contractor or do extensive renovations to add value to your home.
