Got a call from this number. Said they were with the Breast Cancer Society. Asked me what credit card I would like to place my pledge on. Told them to mail me a pledge form. I do not donate with a credit card over the phone. Then they asked me if I wanted to use any of my visa gift cards or paypal. Told them to mail me the form. They were polite the whole time, but I was not feeling comfortable about the whole thing. IF I get a pledge form, I will definitely research it first!
Chances are very good that only a tiny portion of any move you would give to these telephone solicitors would actually go to the charity. They often keep 85% or more of donations for "administrative costs". If you really want to donate to a charity it is always best to contact the charity itself and donate directly to them. However, you also need to research the charity itself to see what they do with donations and what percent actually goes towards the cause supported by the charity.
