Now when I donate I tell them "if I receive even one piece of mail soliciting funds you will never receive another donation". None have complied which is why now I only donate cash.
charities sell mailing lists
I got pretty nasty with PBS some years back when I realized they sell subscriber’s mailing lists. Course that was before I realized how far off base they are with their “newscasts”. My letter did stop their mailings to me. Now if I can just convince AARP to get off my back. They are better than they used to be but they resurface once or twice a year.
