I am about a week behind on passing along this information, but the Goochland Farmer's Market Winter Food Co-op that runs through April 30 has cut it's registration fee for those who join after February 1st. This Co-Op is part of the Lulu's Local Foods Website run by Molly Harris.
To register go to http://gfm.luluslocalfood.com. For the Goochland Co-Op you can place an order via the website each week starting on Wednesday evenings and can add to your order through Sunday morning. This Co-Op group offers two pick up sites within Goochland on Tuesday afternoons.
