The Local Dirt app allows users to locate, buy, and sell local foods in their area. Launched in early 2008 in Madison, Wisconsin, the concept not only supports local economies, but also cuts out the high emissions spent on transporting grocery products across the country. Better yet, Local Dirt is funded by the National Science Foundation, so it's free for the rest of the year. Unfortunately, this perk ends December 31, 2012; from that point on, membership will be $360 annually. Still, this is a low price to pay for access to fresh, local products year-round, and chances are you'll still pay less than you would at your local Whole Foods (WFM). Businesses and large organizations can typically have their orders delivered; individuals usually have to go to the source to pick up their local goods.
