While I only have one under my name, I was technically good for three of those Vaders (my phone order, my wife trying on the computer at work, and my best friend on his account). I'm surprised at how easy it ended up being to get.
So now I've got mine, and my friend is going to sell the one he ordered for me to another good friend of ours who couldn't get one.
This bodes well for Darth Maul...whenever he gets around to being pre-ordered.
