Looking for Barbapappa

I've been to Paris, France twice in the past two years and only bought one of the Barbapapa books that I loved as a child. Now that I'm expecting my first child I really want to find the initial series of the books. Unfortunately the website is not very helpful as it only tells about the series not where to find the books in the US. I'm trying to figure out a way to get them. Any suggestions????? Anyone going to France soon? I'll send Euros for the books to be sent to me!
