When a cousin was going to a certain college, an aunt got a coffee mug from that school and rolled many $1 bills and put them in the mug.
I am thinking about Christmas this year, and cash may be a substantial part of the gifts. I’ve thought of just getting multiple bills and wrapping them individually in different sized boxes/bags.
One Christmas I have cash, but I put things the kids already owned in boxes so they wouldn’t know it was cash.
