Cathmom,
I may not have seven children yet, but I am in a similar situation, so being really rabid when saying that I'm overly obsessing about what goes into my body is very judgmental.
Since we're talking about how much we make now, we make less than $30,000. I have five children, and one is mainly still nursing.
I don't drink tap water. Ever. I get the reverse osmosis water (which takes the vast majority of contaminants out of the water) from the store for 30 cents a gallon. I know what's in the water. I also know that not all of it can be taken out (not even all the fluoride, no matter what kind of filter you have.) I know what they add at the plant, and what people flush down the toilet. I know that the medication people are flushing gets into the water, and that's why I don't drink it, and certainly not my children.
I live in a "marginal neighborhood," where, if you go a few blocks away, there are a couple of gang houses. When you talk about protecting souls, and that we must be worried about that, I do my best. I homeschool, and I try to go to daily Mass. What I read (and perhaps, forgive me, inferred) is that I should be more concerned about the salvation of the souls that God has put me in charge of, than what they put in their bodies, and if you read anything that I have posted prior to this, you, perhaps, would see that it is my main focus, however, there is nothing wrong with keeping them away from contaminants I know could psychologically and physiologically damage them. Saying I "obsess" about these things is a very big exaggeration.
For me, having to budget to be able to afford it was a very big task (considering, now, that perhaps even I have less money to work with than even you do), but if you adjust gradually, it makes it easier, at least from my experience. Doing it all at once before you know what brands are the most cost-efficient, is a very big headache, and one that I wouldn't recommend.
I am not trying to point fingers at anyone here, and I believe it's tragic that people could have taken it that way. I'm trying to show you what I've researched, and hopefully it will make it a bit easier to make your decision about what you choose to eat.
Writing off organic simply because it's more expensive, I believe, is a mistake. I'd rather spend $20 more on a product made by workers in the United States, or Wisconsin, even, so that my neighbor could keep his job, rather than buy the cheaper thing for much less and support some big corporation enslaving Chinese people.
Most of the time, saying yes to organics is saying no to globalization, which has gotten the US in the mess it is in right now.
Anyway, if I offended you, Alex, or Cathmom, I'm sorry. People say I am rather blunt, and my writing evidences that.
