BookFunnel is a book delivery service. They are of two varieties: 1. One that collects emails, and 2. One that does not. If you are clicking a BookFunnel link in our cross-promo landing page, I can almost guarantee you it is the one that collects emails, since that’s the whole purpose of offering that story for free.
BookFunnel, at least, has some awesome customer service if you have trouble getting your book.
