Great App if you want to pay every year

This app is excellent. I have no issue with the content, its functionality, nothing. Ive had it for years. But this year, I refuse to pay another $40 for a book every year. Im very disappointed. I actually really, REALLY like it. But I cant see having to pay year after year for the SAME book.
Im really disappointed to lose this one. But its the principle of it all.
