A nine-year-old Indiana boy has started selling popcorn door-to-door to raise money for his grandfather. After hearing that his grandfather needed a heart transplant, Owen Holmes started using his own money to buy popcorn from his favorite shop, Shirley's Gourmet Popcorn, and sell it door-to-door with his mother and eight-year-old brother. So far, Owen has brought in $300 and has upped his goal to $500.
