they didn't have to sell your info- once you give to a large charitable organization your information is automatically on the (LIST) as someone who gives. we get 25-40 requests (weekly!) from everyone out there.
i did send to one with a note stating that if i received any thing from them for the next year i would never give to them again-once a year only! so far (2 months now) i have not been inundated by that one...but i don't want to send to everyone --- so havent figured out how to get them to stop.
i wish there was something we could call-like the 'do not call list' to be removed---hmmm....maybe there is??????? will have to look. seems like there should be.
