Kable (a US distribution company) wil be managing their webstore in a near future, they said they will have a more affordable shipping solution. You should wait until then to see if the price is right.
You can also try on the Tric Trac thread for this game, a lot of french backers will only use the french updated cards maybe you could find one that don't want their pack of cards.
Merci. Je viens de poster une demande dans le forum.
