Reusing boxes is a great idea! But as an alternative to the post office boxes (as I agree they are not free to the postal service unless they have been used as their intended purpose) I collect used cereal boxes and tape them together for box strength. It's perfect for a homemade mailbox/paper center:) and it usually is a cool art piece too with the many different patterns on the cereal boxes.
