Best Buy offers Assassin's Creed III for PlayStation 3 or Xbox 360 for $34.99 with free shipping. That's $10 under our mention from two weeks ago and the lowest total price we could find for either platform by at least $15. Sales tax is added where applicable.
Update:Microsoft Store now offers the Xbox 360 version (pictured) for $24.99 with free shipping. Update: Microsoft Store has since sold out, but Best Buy's price is still available and the second best we've ever seen.
