Sam's Club offers its members the Hisense 54.6" 4K 2160p HDR LED-Backlit LCD Ultra HD Roku Smart Television, model no. 55R6D, for $348 with free shipping. (Non-members pay an extra $34.80.) That's tied with our mention from a week ago as the second lowest price we've seen for any 55" 4K Roku television. (It's the best deal for this model today by $218.) It features a 3840x2160 (4K, 2160p) native resolution, full-array LED backlight, 4K upscaling, built-in dual-band WiFi, Roku media streaming (including Netflix and Hulu), USB input, and three HDMI inputs.
