Walmart offers the refurbished TCL 55" 4K LED-Backlit Ultra HD Roku Smart Television, model no. 55S401, for $335 plus $19.97 for shipping. That's $43 less than our September mention and $45 under the lowest price we could find for a new one today. It features content streaming via Roku TV (Netflix, Youtube, Hulu Plus, more), USB, and three HDMI inputs.

Note: A 90-day warranty applies, but it's unclear who backs it.
