I usually shop @ Trader Joe's or Whole Foods... mainly because I am fairly picky about what our family eats. My sister is involved in a co-op where she lives and saves quite a bit of money. When you say Bay area do you mean South Bay, are you local? I'm in Redondo Beach...
I'd be interested in joining if I could find
* Organic produce
* All natural cleaning products
* All natural bath / body products, etc.
Let me know if this is what you are looking for in a co-op as well and if you are local to me :)
