For its members only, Sam's Club offers the Samsung 50" 4K 2160p LED-Backlit LCD Ultra HD Smart Television, model no. UN50KU6290, for $448 with free shipping. That's $201 under the lowest total price we could find for any 50" 4K Samsung television. (For further comparison, on Black Friday we saw a comparable model for $48 less and bundled with a $100 Dell gift card.) It features a 3840x2160 (4K, 2160p) native resolution, 4K upscaling, 802.11ac wireless, Smart Hub (with access to Netflix, Pandora, Hulu, etc.), USB, and three HDMI inputs.
