It's too expensive to get a chapter. You can not save up ivouchers to read a few chapters at once or the book and they have to be used in a week. I've wasted hundreds of stupid vouchers because I didn't have time to read. You cannot watch ads to get any free chapters. I want to read but I'm not going to spend more for one book than I do for kindle. It's just not worth it. If I could give zero stars I would.
