How can a dime a day make a difference?

I was talking to a friend about this Web site and they said they didn't believe that donating just a dime a day would make a difference - it only adds up to $3 per month and what could a charity do with just $3 a month. I explained that the important figure wasn't the size of the donation but, rather, the number of donations. If he donated a dime a day, and I added that to the dime a day donated by 100 other people, that would be more than $300 per month. If I added his dime a day to that of 1,000 other people, that's $3,003. I believe that charities need, and are grateful for, donations of any size. So make a difference and committ to donating A Dime A Day to your favorite charity.
