Input: Text: so apparently amazon is giving out free 30-day trials to kindle owners, where you can download books for free. i took it up immediately, why not? being the greedy pig i was, i went on a massive romp downloading all manners of books i could find.
the catch:**you can only download books within their kindle unlimited selection**
it was only after reaching my creditcard limit,and after racking up tons of books, before i thought that something was wrong. i proceeded to check my orders and to my dismay.... you guess it.
apparently you can't cancel your digital book downloads, because it is easy to copy the book onto your cpu and cancel the order. guess i won't have to buy books for a few decades now.
