I love adding bouncy balls to my boxes. I try to add one or 2 to each box. One of my favorite places to pick up balls is Old Navy. .25 cents in their vending machine. No tax. You can't go wrong.
And this weekend when as I was searching for quarters a man walked up to my boys and asked if they each wanted a ball. The machine had dispensed 3 of the exact same ball. And they wanted all different styles. So we scored 2 free balls! I just smiled and thanked Jesus. And then found a few quarters and bought some more:)
