As much as possible, but yes, it is pricey, so I am far from perfect about it. Some things I won't buy unless organic - celery, berries, dairy. All other fuits and veggies I buy organic local if I can find it. If not, I get local non-organic, and comventional only when I hav eno other choice. I get organic chicken, eggs, hamburger, and hope to get more organic beef, but right now convincing hubby it is worth it is tough. Beef is especially pricey organic.
