I made the mistake of not immediately downloading and backing up a book I "purchased" from Apple's Book Store. When I went to download it some months later I found it had been removed from the store and could no longer be downloaded. No refund was offered. I had expected it to work like Apple's App Store, where as far as I can tell you can generally still download apps you've purchased (although older apps often do not work with newer devices and/or iOS versions.) Since then I've moved to PDFs or Kindle. If Amazon pulls the same trick I may have to rethink my strategy.
