[Ludovico Slongo]

I want to buy this three volumes series but I discovered that the book is a self-published one and it seems that the author accepts only "chèques bancaires" that is a rather difficult way of payment for me -in particular if made towards a foreign country.
Do anybody know if any French bookseller exists that could sell me those books accepting a different way of payment (i.e. credit card)?
Now another question (not related to the above one but to French language), do anybody know if "carte bancaire" is the exact equivalent of credit card?
Thanks in advance
