Sam's Club offers its members the Samsung 6 Series 64.5" 4K HDR WiFi LED LCD Ultra HD Smart Television, model no. UN65MU6290, for $798 with free shipping. (Non-members pay a $49.80 surcharge so it's better to opt for a 1-year membership, which costs $45.) Excluding the mention below, that's the lowest price we could find by $100, although we saw it for $40 less six days ago. This 2017 model features a native resolution of 3840x2160 (4K 2160p), HDR Pro, WiFi, Ethernet, Bluetooth, Smart TV apps (Netflix, Pandora, Hulu, etc.), two USB ports, and three HDMI inputs. Deal ends December 2.

A close price: Dell Home charges $799.99 with free shipping.
