Walmart offers the refurbished Samsung 64.5" 4K 2160p Curved LED-Backlit LCD Ultra HD Smart Television, model no. UN65JU6700, for $899.99. Opt for in-store pickup to dodge the $49.97 shipping fee. That's tied with our April mention and $318 under the lowest price we could find for a refurb now. It features a 3840x2160 (4K) native resolution, LED backlight, curved design, WiFi, SmartTV applications (including Netflix, Pandora, and YouTube), three USB ports, and four HDMI inputs.
Note: No warranty information is provided, although the seller does offer a 90-day return policy.
