I do. You should add, in italics, a line like the following--with Infestation and Peaceful Quiet Lives hyperlinked to Amazon--to your posts before the Medium affiliate link. You don’t need to say anything promotional beyond it. Give your readers credit for being smart enough to figure out that a hyperlink will probably take them to a place where they can buy a book or at least learn more.
