I remember book clubs. A big magazine would come in the mail and I would select the books I wanted for the next mailing. If I didn't want any I had to send in a no reply by mail. I always thought it was wrong for the customer to have to say they didn't want something or it would be sent to you. The one I enjoyed the most was Reader's Digest Condensed books. Five books in one! I moved and had a nice library to go to so I stopped the book club.
