(AREA) -- This Saturday, Campbell Soup Company will once again join forces with the National Association of Letter Carries to support Feeding America during Stamp Out Hunger. Now in it's 21st year, the Stamp Out Hunger food drive benefits the largest domestic hunger-relief organization. Last year, letter carriers collected food donations from 10,000 communities, helping put millions of meals on the tables of Americans in need. The food drive will be held this Saturday, May 11. To participate, residents are encouraged to leave a sturdy bag containing non-perishable foods next to their mailbox prior to delivery. The drive is important for local communities by stocking food banks and pantries during the summer months when there is an increase for food assistance.
