Walmart offers the refurbished Samsung 54.6" 1080p Curved LED-Backlit LCD HD Smart Television, model no. UN55K6250AFXZA, for $479.99. Opt for in-store pickup to cut that to $468.95. That's $11 below our mention from a week ago, $279 under the lowest price we could find for a new one today, and the best price we've seen. It features WiFi, Bluetooth, Smart Hub apps (including Netflix, YouTube, and Hulu Plus), USB, and three HDMI inputs.
Note: A 90-day warranty applies, although it's unclear who backs it.
