Walmart offers the refurbished LG 54.6" 4K HDR IPS LED-Backlit LCD Ultra HD Smart Television, model no. 55UJ6300, for an in-cart price of $399.99 with free shipping. That's $69 less than our mention of a new one from two days ago and $136 under the lowest price we could find for a new unit today.

It features a 3840x2160 (4K, 2160p) native resolution, active HDR, 4K upscaling, 802.11ac wireless, webOS 3.5 (with access to Hulu Plus, Netflix, YouTube, more), USB, and three HDMI inputs.

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