Donate Some of Your Donation to Charity

I read an article from Forbes that said, "Some for-profit fundraisers who call on behalf of charities may keep anywhere from 25 to 95 cents of every dollar they collect".  With all of the natural disasters that have occured, I would like to donate money to help in the aftermath, but not when as little as 5% of my donation could be making to actually help the cause.  Another quote that shocked me was, "Their research shows less than 10% of the American Veterans Relief Foundation's expenses go towards the actual program while 83% of its spending goes towards fundraising".  This is also if your money gets donated to a legitamate charity, and not just a scam that can process credit cards to steal your money.  I could not find definate figures on the Red Cross, but I just think about how many times I see a sign, a commercial, or an internet advertisement; all of which cost lots of money.
Do you feel charities are overmarketing in times of disaster, or people wouldn't donate unless it was put in front of them?
