1. For signing me up for a “preview” program when I ordered one of your books — no doubt because I neglected to toggle a checkmark in some tiny opt-out box on your website, thereby “signing up” for this “service” — and then sending me a new book, which I have to mail back if I don’t want to pay you for it.
2. For including an invoice that says I have to pay for the return postage, not revealing until I called to complain that I can print out a postage-paid label from your website.
I’m going to the post office now with their book and their label to mail this back. A person more vindictive than I would include a brick.
