I'm posting this in the mounts and pets forums as I believe you have to buy the game (as well as subscribe for 2 months) if you want to recruit-a-friend and get a mount or pet out of it. Right now that works out much cheaper
If you select the "gift it" option and supply your own email address then it will email you the code, to use later at your leisure. I think if you don't select "gift it" then it wants to apply it to your own account as you're currently logged in.
