I've just discovered www.bountifulbaskets.org and I think it's going to change my life and the way I shop! I picked up my first basket this past Saturday and it was quite the experience and I was impressed. It's a food co-op and it's volunteer based, so no one is paid and your $16.50/basket goes all into the food you buy! I have to admit that I had fun waiting for the semi-truck to arrive and then we had to unload the truck and divide the food among the baskets.
You should try it out for yourself! I hear that the produce is so fresh that it will last a couple of weeks.
