Generally, locally grown is considered to be grown and consumed within a 100 mile radius. We have a little more wiggle room in the Hawaiian islands, because let's face it, the Big Island is much closer at 121 than the 2500 to the mainland.
Corporate giants such as Frito Lay, McDonald's, Starbucks, HSBC, Unilever and Walmart are using localwashing tactics in their marketing and advertising. Showing a farmer in an ad, does not make the potato chips local by the time they reach their destination. Removing the corporate name and rebranding the store does not mean it is locally owned, it's deceptive localwashing at it's worst.
For every $100 spent at a locally owned store, $45 stays in the community. Only about $13 stays in community when it is spent at a chain store.
