Walmart offers the refurbished Samsung 64.5" 4K 2160p LED-Backlit LCD Ultra HD Smart Television, model no. UN65KU6290, for $699.99. Opt for in-store pickup to dodge the $49.97 shipping charge. That's tied with our mention from two weeks ago and $199 under the lowest price we could find for a new unit. It features a 3840x2160 (4K, 2160p) native resolution, 4K upscaling, Smart Hub (with access to Netflix, Hulu Plus, Amazon Video, more), and three HDMI inputs.

Note: No warranty information is available, although the seller does offer a 90-day return policy.
