Leanpub used to offer a $99 Flat Fee option for individual books or courses. We do not do this now. Instead, we are all in on the Freemium + subscription model.
The Standard and Pro plans offer great value for their low monthly price., and they let you create up to 100 books or courses. We want authors creating lots of books and courses!
Also, with the introduction of Freemium, we now have the same 100 books or courses in our Free plan. So, no one ever loses access to their books or courses. This concern was the main reason that we had created the Flat Fee option, and it's now a non-issue.
