Walmart offers the refurbished TCL 55" 4K LED-Backlit Ultra HD Roku Smart Television, model no. 55S401, for $339.99. Opt for in-store pickup to avoid the $19.97 shipping charge. That's $15 under our mention from three weeks ago and $110 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.
