Corporate involvement in buying local goods

With many more consumers including myself looking to purchase locally there has been a slow but growing segment of large retailers that has started to take notice of this growing demographic and they have started to make changes. Companies such as Meijer, Wal-Mart, and Chipotle grill among others are adding local goods to their selection. Meijer has a section solely devoted to Michigan made goods. While the section is small now, it makes it easy for people like myself to see the local goods they carry. Wal-Mart has "committed" to buy more local produce when it is in season. I don't go into Wal-Mart often, especially for produce, but when checking it out recently I found no way to identify anything locally grow. This could be because it's currently December and most things are out of season, maybe in the southern part of the country you would have better luck. Chipotle has committed to purchasing "food with integrity". This includes purchasing foods that is good for animals (without antibiotics or addition hormones), people, and he environment. If you haven't been to Chipotle I highly recommend it. One opened on West Main in Kalamazoo around a year ago. It's comparable to Qdoba, but I like the fact that they support the environment more than most corporate chains. Here's a Chipotle commercial that aired during last years Super Bowl. http://www.youtube.com/watch?v=aMfSGt6rHos
