bro why's it so expensive?

theres a subscription to get it, another to buy books, and more. whats the best way to get audible? how can i scam it to get it for free? do they have free trials or just the $0.99¢ + paying for books? how does the credits system work? can i just create new accounts for free trials and do all books come in that? do credit books count in free trial?
