Walmart offers the refurbished Vizio 55" 120Hz 1080p LED-Backlit LCD Smart HD Television, model no. E550i-B2, for $429.99 with free shipping. That's tied with our mention from a week ago as the lowest total price we've seen. (It's a current low for a refurb by $90.) It features a native resolution of 1920x1080 (1080p), 120Hz refresh rate, full-array LED backlight, SmartTV Internet applications (including Netflix, Hulu Plus, YouTube, and more), WiFi, USB, and four HDMI ports.

Note: A 90-day warranty applies, but it's not clear who provides it.
