Walmart offers the refurbished TCL 54.6" 4K LED-Backlit LCD Ultra HD Roku Smart Television, model no. 55US57, for $242.44. Opt for in-store pickup to avoid the $19.97 shipping fee. That's $98 under our November mention and $158 under the best price we could find for a new one. It features a 3840x2160 (4K, 2160p) native resolution, 802.11ac wireless, built-in Roku TV (with access to Netflix, Youtube, Hulu Plus, more), USB, and four HDMI inputs.

A 90-day warranty applies, but it is unclear who backs it.
