I was a member of NOWBC until my area where I live was taken out of the service area. Too bad! In the time that I used the service, it was really good. Basically, it's like a farmer's market where you place an order online and your stuff gets delivered to a local drop point (neighbour's home). That's it. Veggies are usually picked the day before or at most two days before -- so it's super fresh. The best part is that the farmers don't have to drive all the way to the farmer's markets on the weekends, and neither do you -- win win.
Cons: Service mainly to Vancouver areas
