If you haven't picked up Assassin's Creed IV yet, today might be the best chance you'll get before the holiday.  Amazon.com's Gold Box deal today offers you the PC DVD, Steam, Uplay, Xbox 360 and PS3 versions for just $29.99.

Just keep in mind that the Amazon Gold Box deal ends at the end of the day!

That is half off the current Steam price and based on my time with the game, and reviews in general, Assassin's Creed IV is much better than AC3 and currently sits at a score of 87 on Metacritic
