Walmart offers the Samsung 64.5" 4K HDR Flat LED Ultra HD Smart Television for $679.99 with free shipping. That's the lowest price we could find by $20, although most stores charge $798 or more. (We saw it bundled with a $250 Dell gift card for $798 last week.) Features include: 3840x2160 native resolution Smart TV apps (including Netflix, Hulu, YouTube, more) HDR10, HDR10+, and HLG 3 HDMI inputs, 2 USB ports
