I struggle with the organic thing. Part of me really wants to go organic/natural with everything. But, the other part of me knows that I can't possibly afford it. So, I try to strike a balance. We go organic with meat, eggs, milk and yogurt. I also like to by organic produce when it matters...but sometimes I just buy local that isn't necessarily organic.
When it comes to snacks and other dry goods, I just try to make more of them at home, rather than buying high-priced organic/natural snacks. That way I can make sure I know what's going into them, I can do it in bulk and I don't have to spend an arm and a leg. I have a plan to swap with friends too.
I wish I had the motivation to grow a garden of my own...but I seem to put it off every year.
