I have just done my first group buy through green smoothie girl.com last fall. She has a huge selection of raw, organic foods to buy in bulk once a year. It is worth it even with the shipping cost. I got 50 lbs of raw organic almonds and raw organic cashews, and there are so many great things to do with them. I soak and dehydrate them first for an exponential increase in nutrients, plus they get even more crunchy that way. I've made cashew cream, cashew sour cream, cashew and almond cheeses, crackers, spiced nuts etc, all raw and organic. No need to worry about chemicals. I even made a tiramisu all out of cashews and almonds!Since I didn't know what PPO was about I looked into it and found 2 interesting articles for those who are ignorant on the subject.
I hope this information is helpful.
