I mostly bought penny candy. But pennies add up. I was impressed with a book I read that said, if someone wants to give you a million dollars in pennies, tell them where to deliver it on your lawn (you can pay someone to roll it or deliver it to the bank if need be) as it's still a million dollars. The New Ageish book's point was that people look down on, won't pick up a penny in the street, but if you don't pick up a penny, why should the Universe entrust you with more? You have to care about the small stuff before the big stuff will come.
