@Lluis_Revilla I don't have any input or control over Routledge's promos (if you are referring to the inspection copy that instructors of courses can request, I believe that is something you would need to request directly from the publisher if you are an academic instructor, and is a different process than simply buying as an individual). For ebooks, I've listed the options that I know about, but I can't test their cross-compatibility. Kindle format is available directly on amazon though!
