How can I ensure that the clothing I donate to charity really helps the needy? - By Constance Casey. Dear My Goodness, I have a bunch of old clothes I'd like to get rid of, but I'm wary of just dumping them off in one of those yellow bins by the side of the road. I'm not terribly confident that those clothes will end up in the hands of people who need them. I'd donate them to the Salvation Army, but they resell the clothing. Doctors Without Borders.
