For its members only, Sam's Club offers the Hitachi 55" Ultravision 4K 2160p LED-Backlit LCD HD Television, model no. LU55V809, bundled with the Roku 4 4K Wireless Streaming Media Player, model no. 4400R, for $598 with free shipping. (Non-members pay $59.80 more, so it would be best to buy a Sam's Club 1-Year Membership for $45 instead.) That's a $120 savings and the best deal we could find. The HDTV features a 3840x2160 native resolution (four times that of 1080p TVs), LED backlight, USB, and four HDMI inputs. The Roku streams 4K HD content from Netflix, Amazon Video On Demand, Pandora, Flickr, and other media apps; it features 802.11ac wireless, USB, voice control, lost remote feature, and HDMI.
