Sam's Club offers its members the Hisense 50" 4K HDR LED-Backlit LCD Ultra HD Roku Smart Television, model no. 50R6D, for $298 with free shipping. (Non-members pay an additional $29.80.) That's tied with last week's mention and as the best shipped deal we've seen for a 50" 4K TV with Roku. (It's the lowest price today by $50.) It features a native resolution of 3840x2160 (4K 2160p), content streaming via Roku TV (including Netflix, Youtube, and Hulu Plus), and three HDMI inputs. Deal ends December 2.
