Buying Ayu stuff in Paris?

[Empry]

Maybe I should have specified my question better because I was not referring to normal shops of course, but to shops that sell Japanese music in Paris. Bookoff is for example, a chain of shops from Japan that has 2 branches in Paris where they sell used Japanase manga, books, CDs, etc.. I however do not know if they have Ayu CDs or Mags and I would rather not send my parents to Bookoff , or any other shop, to bring me an Ayu gift from their trip if I know that there isn't anything Ayu-related there in the first place.
