Considering the recent rash of people looking to get into the game with the new updates upcoming (which is fantastic), I figured this deal might be of interest to some folks. Amazon is currently selling Final Fantasy XIV for 9.99 in their 19 days of deals PC Games day sale. Not as cheap as a free buddy pass, but if you really want to try the game this isn't a bad deal.
Notice: This is NOT the version that comes with a free Buddy Pass of your own to give out, but it does include the free 30 days (ie if they start charging before your free 30 days are up, you'll still get the free month). The collectors Edition (which has the pass and other bonuses) is available on Amazon's marketplace (not sold directly by amazon) for around 20 plus shipping, just make sure you get a new one and not used.
