Hurry and get it now while you can! Just add it to your cart and make sure you select Pay with Microsoft Points. It will show how much you have and will say Free underneath!
Also some people are having issues getting it to work. You must be a Gold member for it to work. Not sure why but everyone who is a gold member has gotten it to work. Those who are silver members haven't.
