Here at indie author's toolbox we sometimes use affiliate links. This means that if you make a purchase after clicking on one of these links, we make a small commission for referring you to that product. That doesn't mean my opinion is for sale. Most of the links are to books we have reviewed on this site. It makes it easier for you to pick up a copy of the book, if you decide it's something that may be helpful to you. Or if you'd prefer, you can search for the book on Amazon. That way no affiliate commissions are paid.
