Walmart offers the RCA 78" 4K LED-Backlit LCD Ultra HD Television, model no. RTU7877, for $1,099 with free shipping. That's tied with our mention a week ago as the lowest price we've seen for any 78" 4K LED LCD HDTV. (It's a savings of $400 off list.) It features a 3840x2160 (4K, 2160p) native resolution, 120Hz refresh rate, and four HDMI inputs.

Update: Shipping is now $19.97, so it's best to opt for in-store pickup.
