Walmart offers the refurbished Hisense 50" 4K 2160p WiFi LED-Backlit LCD Ultra HD Smart Television, model no. 50H8C, for $329.99. Choose in-store pickup to drop it to $322.40. That matches our mention from last week as the best price we've seen. (It's also $178 under the lowest price we could find for a new unit.) It features a 3840x2160 (2160p) native resolution, Smart TV apps (including Netflix and YouTube), USB 3.0, and three HDMI inputs.
