Micro Center offers the refurbished Sharp 59.5" 4K LED-Backlit LCD Ultra HD Smart Television, model no. LC-60P6070U, for $469.99 with free shipping. That's $30 under our mention of a new one from a month ago and the lowest price we've seen for it in any condition. (It's $60 less than a new unit today and one of the best deals we've seen for a 60"-class 4K TV in general.) It features a 3840x2160 (4K) native resolution, WiFi, Smart TV apps (including Netflix, Amazon Video, and YouTube), USB, and two HDMI inputs.

Note: A 1-year warranty applies, but it's unclear who covers it.

Update: It's now available for in-store pickup only.
