I encourage everyone to join a CSA. I was always hesitant about it at first because you do have to put a lot of money down right away.
We divided how much we spent by an estimated amount of weeks we will get a share and it came down to 11 dollars a week. We got a small share too. Eleven dollars for all this food. Not only is it local, but it's also organic (well they can't technically use that term, but it pesticide free). I don't know where else you can get this much organic produce for that little.
