Is Bug Bluff available in an English version or at any US online stores?
Part of the problem could be with the way the game's name is entered in each store's DB. I've often seen "Kakerlaken Poker", "Kaker Laken Poker", & "Kakerlakenpoker", because the box isn't as to whether or not those really are separate words. As for "Bug Bluff", unless I'm mistaken, it's actually... the French name. The English name apparently is "Cockroach Poker". That's what my box implies.
Back to your question... I know that some Canadian online stores, like www.levalet.com, do have that game in stock. And it's a multilingual copy. (In fact, the game is just a bunch of cards with nice pictures - getting an English-specific copy is hardly necessary with the BGG's resources.)
