Finally, a sensible question. You want your money back? Write me a letter, in care of this publisher, expressing your heartfelt dissatisfaction. If I am still alive, and I am really, truly touched, moved, amused or impressed with your reasoning for why you feel you should get your money back, I will send you your $2.95 or whatever it was you paid.
Keep in mind I will have your address, and I might also mail my corpse to you when I die.
