Years ago, KHNL ran a campaign encouraging local consumers to "Buy Hawaii First". The premise was simple--when you make your choices on goods and products and when value, quality, and price are equal, why not support your neighbor, your friend, your local business.
That concept is still true today. No, this is not xenophobia, or fear of outsiders. It is simply an acknowledgement that when we buy from people or shops that grow or make their goods locally, we help our fellow residents and the local tax base.
