I need to buy Scars of abyss where can i buy it? -.-; since its just the new one showing at the thingy
You can buy it right from Playonline.
They have it advertised on the main FFXI login screen where you hit "Play". If you want to buy a specific one, you should be able to find a submenu there to purchase specific expansion packages.
