Walmart offers the refurbished Vizio SmartCast E-Series 69.5" 4K HDR Flat LED Ultra HD Smart Display for $649.99. Opt for in-store pickup to cut that to $643.43 and avoid the $19.97 shipping charge. That's tied with last week's mention as the best price we've seen. (It's a low by $127 for a refurb today.). This tuner-free display features: 3840x2160 (4K) native resolution HDR10 802.11ac wireless and Bluetooth 4.1 Vizio SmartCast with built-in Chromecast 4 HDMI inputs Note: It comes with a 90-day warranty, although it's unclear who backs it.
