Walmart offers the Polaroid 65" 4K HDR Flat LED Ultra HD Smart Television, model no. 65T7U, for $389.99. Opt for in-store pickup to avoid the $49.97 freight shipping charge. That's the best deal we could find for this model by $390 and the cheapest 65" 4K HDR TV we've seen. It features a 3840x2160 (4K) native resolution, smart TV apps (including Netflix, YouTube, Vudu, more), and three HDMI inputs.

Orders placed with free shipping by 2 pm local time on December 18 are expected to arrive in time for Christmas.
