Walmart offers the refurbished Samsung 40" 4K 2160p LED-Backlit LCD Ultra HD Television, model no. UN40MU6300FXZA, for $369.99 with free shipping. That's $28 less than last week's mention of a new TV and the best deal we've seen. (It's $28 under the lowest price we could find for a new one today.) It features a 3840x2160 (2160p) native resolution, Smart TV apps (Netflix, Pandora, Hulu, etc.), USB, and three HDMI inputs.

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