Once you get off the waitlist, they make it reall easy to maintain your subscription even if you have to skip a month or two. They always send out emails before the subscription renews so you can choose if you want that book or not. This is my favorite part about it because it gives my the control. THere have been several months i have skipped the book because I just didn't want it. And I was able to pick it back up the next month without any problems.
