Sam's Club offers its members the Vizio 50" 4K 120Hz LED LCD Smart Ultra HD Television, model no. P502ui-B1E, for $698 with free shipping. (Non-members pay an additional $69.80, so it's best to buy a 1-year membership for $45.) That's tied with our mention from three weeks ago and the lowest price we could find now by $200. It features a 3840x2160 resolution, 120Hz refresh rate, 2-sided remote with QWERTY keyboard, USB, and five HDMI inputs.
