I have stopped giving to several charities that continue to send me unsolicited gifts, like greeting cards and address labels, among other things. I would rather any donation money be applied to the cause for which it was raised, rather than wasted by fundraising come-ons. I also ask to be removed from their mailing lists, which has never worked. I also use the link that pnd has provided. Money giveen to a charity for a specific cause should be used for that cause, with a minimization of unnecessary expenses.
