I have a question about frequency of use of Credit Cards in international selling process.
From your selling experience, which credit cards are most used in your International selling? How important is to have Diner's, Optima, Carte Bleue, JCB, Maestro, Solo ... covered as an option for successfull selling, as addition to big US four (VISA, MasterCard, American Express and Discover)?
Thanks in advance for your time and efforts answering these questions.
