DO A GOOD FEED

If you’ve ever taken your lunch money for granted, why not help out a fellow schoolkid in need by buying a FEED bag? For every canvas FEED Haiti bag purchased, 50 school meals will be donated to the United Nations World Food Programme’s School Feeding program. Or opt for the FEED Japan bag to contribute to the FEED Japan Fund, which aids in earthquake disaster relief.
