I just keep my change in a jar-type deal I have in my apartment, and then when it builds up, I pass it off to my friend. Her bank apparently has a Coinstar-ish machine or something of that nature, but the best part is that it doesn't take anything away from you if you have an account there. So, that works for me, obviously. Sometimes it's good to have friends who... well... have bank accounts at a different bank.
