Ah, I didn't know the preorder cases ever came sealed, and I didn't know there was an AUS version. I have a UK copy with the poster inside but not for sale unfortunately. You know the preorder bonus was just the case/poster and no game inside? The game came inside a standard case, so you ended up with 1 cart and 2 cases if you preordered it. Get the UK or AUS version so you get one with English text on the sticker.
Seems totally random to me but yeah
Greece definitely had the best preorder bonuses for this game. The US got no bonuses. Greece got a hat, 3DS slipcase, keychain, plastic ocarina, and best of all a little can of Deku seeds.
