Walmart offers the refurbished Samsung 54.6" 4K 2160p LED-Backlit LCD Ultra HD Smart Television, model no. UN55JU6500, for $469.99. Opt for in-store pickup to cut it to $459.18. (Kmart charges a few cents more.) With free shipping, that's $71 under our refurb mention from March, $241 under the best price we could find for a new unit, and the lowest price we've seen for this TV in any condition. It features a 3840x2160 native resolution (four times that of 1080p TVs), 802.11ac wireless, Smart Hub (with access to Netflix, Hulu Plus, Pandora, Amazon Video, more), USB, and four HDMI inputs.
