They (bookbudd.com) claim not to charge your credit card for the trial period but will do so anyway, even if you cancel before the trial period is up. Also, they will charge you to cancel your free registration, and will periodically charge your credit card for an undetermined of money. And, the website doesn't have some movies, books, and music it has advertised. I think this is another trick used to lure potential victims to the website.
Online user who have already subscribed to bookbudd, are asked to contact their credit card company or bank for help to prevent the fraudulent website from fraudulently charging their credit cards, or refund their money if their cards were already charged.
