Walmart continues to offer the refurbished Samsung 55" 4K 2160p WiFi LED-Backlit LCD Smart Ultra HD Television, model no. UN55HU6840, for $449.99. To drop the price to $439.64, opt for in-store pickup. That's tied with last week's mention as the lowest price we've seen. (It's also the best deal we could find today for a refurb by $260.) It features a 3840x2160 native resolution, WiFi, Smart TV apps (including Hulu Plus, Netflix, YouTube, and more), USB, and four HDMI inputs.
Note: No warranty information is available.
