I just finished reading a Kindle ebook and sent Amazon a dozen minor typos (mostly hyphens left in when words were unsplit). I didn't complain or ask for a refund -- I just sent the list culled from my clippings file (handy way to note such things). The reply from Amazon was boilerplate apologizing for the errors, promising a full refund and telling me the book will be removed from my Kindle. This seems a somewhat aggressive way to solve the problem, but perhaps it works out cheaper for them in the end. I read the book, enjoyed it and now it's free. Perhaps this is a good reason to send in bug reports, but wait til you have finished the book before doing so.
