Indygal: My husband and I did do the Food Stamp Challenge trying to eat only organic and buying majority of our groceries at local Farmer's Markets just to see if we could. We found that while it was hard, it wasn't impossible. We managed (but did go a little hungry sometimes and ate less food than normal...and lost weight). I would drag around a notebook and try and compare prices and noticed that Farmer's Markets were higher but we just bought less food and wasted almost nothing unlike pre- and (sadly) post-challenge. Farmers were also very supportive and would throw in extra produce (something that NEVER happens at Vons).

I think the goal is, do what you can and what feels comfortable for you. We try but we're not militant. And yes, it would be harder if we had children or the luxury of a car, etc.
