I just learned about these guys at the Green Festival in SF and got my first delivery of wonderful (and very affordable) organic fruits and vegetables from their farm in Davis. This is a cool, family-run company. A bit from their website:
Farm Fresh To You is currently the only bay area produce home delivery service who is also the farm, will deliver to your home or office, does not require any commitment, and allows you to customize what you receive in your delivery, based on seasonal availability. We also strive to connect customers with the people and processes in which their produce is grown with farm tours and weekly farm newsletters.
