Aside from the external package, what exactly do the letters 'J', 'Q', 'K', 'A' and the word 'Joker' translate to in French? It can't be that hard to repackage a deck of 52 of cards. The same can be said for shipping. It might cost some extra dollars to ship worldwide, but it's still just a deck of cards. shipping isn't going to break the bank.
So, yeah. I'd say licencing is the reason for the exclusive region US sales. I'm just grateful it's not another dick SDCC exclusive. Those things suck.
Honestly, I'd love to get my hands on a pack of these. They look terrific. So screw Amazon. Ebay is the answer.
