Walmart offers the refurbished Sharp 1080p 40" Flat LED Roku Smart TV for $179.99. Choose in-store pickup to drop the price to $178.17. That's $2 under our mention of a new one from last November and the lowest price we could find for a refurb now by $42. It features 1080p native resolution, Roku streaming apps, and three HDMI inputs. Note: A 90-day warranty applies, but it's unclear who backs it.
