I've been a customer of The Lands at Hillside Farms for the 4+ years that I've lived in the area. They have locally produced milk (both from just their farm and from local dairies - in reusable glass bottles), wonderful ice cream, a newly expanded grocery area (with meat, local baked goods, eggs, cheese, etc.), a mercantile shop (crafts, many locally made) and a series of greenhouses along with a growing garden and plant area. They also have a partnership with a local CSA, several areas to view various animals, and plenty of other facilities - see their website for more details.
Again, Lands at Hillside Farms is a local gem, and I'm glad to live nearby!
