I transfer it from my car and/or purse to my kiddo's piggy bank (stormtrooper head bank). Once it's full, we take it to a Coinstar at Walmart and he gets to spend it on whatever he wants. Not to worry. I do also have a savings account for him that I contribute to every payday and where holiday/birthday money goes. This is just "for fun" money for him. Also, I try to keep quarters in my purse for the occasional toy/gumball/candy machine.
