Walmart offers the refurbished TCL 54.6" 4K 2160p LED-Backlit LCD Ultra HD Roku Smart Television, model no. 55US57, for $319.99. Opt for in-store pickup to avoid the $49.97 shipping fee. That's tied with our mention from a week ago and $79 under the price of a new one. (It's also a great deal for a 55" 4K Roku TV.) It features a 3840x2160 (4K, 2160p) native resolution, 802.11ac wireless, built-in Roku TV (with access to Netflix, Youtube, Hulu Plus, more), USB, and four HDMI inputs.

A 90-day warranty applies, but it is unclear who backs it.
