As parents, we’re all driven to do our best, but sometimes we need to just embrace the messy moments that inevitably come up... Instead of throwing old, unusable school supplies in the trash, find a place to recycle them. Staples offers cash back when you bring in old ink cartridges; TerraCycle will take your used pens, pencils, and markers; and Elmer's will take those old glue sticks off your hands.
