jars of money

You know those coinstar machines, where you dump in your jar of coins and can get cash when you don't have enough money for food or bills? I try not to use them, because I hate to give over 9% of my precious jar of coins, but now they have this thing going on, I don't know if it's just for the holiday season, but they waive the 9% fee if you have the coins turned magically into an amazon.com gift certificate. I thought that might be helpful info. You could buy your xmas gifts with your spare change and that would be great!
