For its members only, Costco offers the Vizio SmartCast E-Series 80" 4K 2160p HDR XLED-Backlit LCD Ultra HD Smart Television, model no. E80-E3, for $2,599.99 with free shipping. (Non-members pay an additional $130, so it's better to buy a membership.) That's $300 less than our August mention and the lowest outright price we've seen. (It's a low now by $398.) It features a 3840x2160 (4K, 2160p) native resolution, full-array XLED backlight, 4K upscaling, 802.11ac wireless, built-in Chromecast (with access to Netflix, Hulu Plus, Amazon Video, and more), Bluetooth 4.1, USB, four HDMI inputs, and Vizio SmartCast capability, which allows you to use your smartphone as a remote via the SmartCast app. Deal ends October 26.
