There are times on this blog when I set up a link to a product. Sometimes, although rarely, these links are affiliate links. If you click on an affiliate link, then eventually buy something, I will get a small advertising fee, free of charge to you.
I will only ever set up links to products I actually use, however, as I don’t believe in selling stuff that I don’t need, want, or use. So, If I’m especially fond of a specific product (be it a book or a service) I might suggest a link for you to follow. These are completely optional.
