The lady on the phone was very pleasant. She was looking for donations for Breast Research and asked if they could send me information in the mail. This did not sound like a scam since she never asked for credit card information or bank information.
This is probably a scam. They call and ask for support of some worth while cause. Ask them what they actually do and enjoy the run around. The owners know as long as they don't lie and say they do certain things it is technically legal.
