Walmart again offers the refurbished Vizio 55" 1080p 120Hz WiFi LED-Backlit LCD HD Television, model no. E550i-A0, for $448 with free shipping. That's tied with last month's mention as the lowest total price we've seen for this TV. (It's also the lowest total price we could find for a refurb by $194.) It features a 1920x1080 (1080p) native resolution, 120Hz refresh rate, LED backlight, WiFi, VIZIO Internet Apps with Netflix, Amazon Instant Video, and Hulu Plus, and four HDMI inputs.
