Highly suspicious. If really a nonprofit, caller was incompetent. Tried to get me to give VISA over phone and when I asked for mailer, hung up. Next day someone called with same number above related to Children's Cancer Fund and same spiel. When I said sure, mail me a brochure - she actually said, ok, bye. I said, aren't you a nonprofit looking for money - aren't you going to send me a mailer for a donation - to which she replied "I don't know how to respond to that". If this is truly legitimate, their callers are not trained
