Your international collection is abysmal... Many authors books/ series are missing, if by chance a series is available then 1 or more titles would be missing. so no point in getting them. Audible search engine needs improvement. Multiple filters cannot be applied at the same time. As soon as u apply 1 filter the filter menu closes. And when you are going through the search results if u open a book n go back the search window closes n u have to start all over again.
