If there's a book that only has e-book versions on amazon, what is the best way to ensure the author gets money? I'd rather not fill my little apartment with paperbacks, and ordering a paperback and then returning it sounds kind of wasteful. Although I guess I could buy a paperback downtown and drop it off at the used book shop .. What do other people do, when they want to pay authors and read e-books without aiding and abetting Bezos?

maybe $author has contact information or even a donate button up somewhere
