Walmart offers the refurbished Samsung 50" 4K HDR Flat LED Ultra HD Smart Television for $299.99. Opt for in-store pickup to cut that to $296.96. That's $81 under the lowest price we could find for a new one, although we saw a refurb for $30 less in January. It features: 3840x2160 (2160p) native resolution WiFi Smart TV apps (YouTube, Netflix, Hulu, etc.) HDMI A 90-day warranty applies but it's unclear who covers it.
