title_body: Why I can't buy books from Kindle Store using Kindle app on iPad? It's really surprising to me to see why it is not easy to buy a book using the Kindle reader app on iPad. It has only provision to download the samples but there is no option to buy a complete book. For that I am using a browser or Amazon Store app. Is there anything I am missing here or it's just like that?
upvoted_answer: Because otherwise Amazon would have to give Apple a cut of the 'in-app purchases'.
