I've been researching about joining a CSA but it seems very involved. You have to go to a drop location once a week (or every other week) and they don't deliver home. I'm busy and too used to get food delivered home by Safeway.
Is it possible to have a box of organic vegetables in season delivered home? (I live in San Francisco).
Yep, I've used https://www.planetorganics.com for years. All organic, and mostly local. More than just produce too, I get my fish/seafood from them and a handful of other things regularly. They have a key to our building so they leave the delivery in a cooler + crate outside the apartment door.
You only mentioned vegetables but I have to also give a big thumbs up to the monthly meat CSA from http://brandonnaturalbeef.com/ which has very reasonable grass fed beef prices and does free home delivery in the bay area.
