Walmart offers the refurbished Hisense 42.5" 4K 2160p LED-Backlit LCD Ultra HD Smart Television, model no. 43H7C, for $259.99 with free shipping. That's tied with our June refurb mention as the lowest price we've seen for this TV in any condition. (It's also $90 less than you'd pay for a new unit today.) It features a 3840x2160 (4K, 2160p) native resolution, built-in WiFi, Smart TV apps (including Hulu Plus, Netflix, and YouTube), three USB ports, and four HDMI inputs.

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