Jimmy-
Well, we'll be accepting credit cards directly, but my understanding, which is limited at this point, is that people were saying that Europeans often don't have credit cards. Anthere reports that the French do, but other reports have suggested (if I understood) that Germans mostly don't?
Last time I checked, CC coverage was only about 15% in Germany, but quite a few cheap offers by VISA & Co. have popped up in the last couple of years, so things may be changing. Still, there's a lot of suspicion concerning "plastic".
Regards,
Erik
