You can buy them directly from Nintendo.
Have you tried getting one from EU/JP? There are quite a lot of them over here. As a lefty, I find it completely invaluable for Kid Icarus
To the OP plz reply to post #18 unless you don't want the poster to purchase the only CPP out there.
From my experience with Gamestop release dates for accessories I wanted to buy a ? plush block and a green shell plush. Initially they had a set release date and when that date came it was then changed to a later date. This cycle happened for three times until finally the plush block was removed from the site and the green shell ended up currently unavailable online.
