I can't imagine Wal Mart having orgainic food any better than the other organic shops I've been in. I don't shop at the other organic shops so I wouldn't buy Wal Mart organic food. Years ago we bought some things at an organic food shop because it was convenient. We quit because they didn't have much selection, products weren't any better and may not have been as good and the prices were out of line. Maybe they've changed but I won't find out.
Walmart already stocks a considerable amount of organically grown products (hereinafter called "organic"). Since last June, I have been buying more organic produce, free range eggs and chicken, fruit juices, etc. - and some of it comes from Walmart, although most comes from a health food store. We continue to buy these items because they taste so much better than the conventionally grown items - and we feel better health-wise when we eat organic food. And it's not just me: my kids (who think Reese's cups and frozen waffles are two of the basic food groups) also have remarked on how much better this food tastes.
I remember how horrible the organic stuff tasted in the 1970's, when I first encountered it. It was truly a penance to eat that junk. No more. I would urge everyone to give it a try, and I think you'd be amazed.
I think Walmart is seeing a trend that is manifesting itself among average American families, like mine, and is going to capitalize on it. Even food giants like Hunts now offer organic tomatoes. There seems to be an underlying trend away from processed food and conventional medicine and a reliance on better nutrition and the use of supplements. Walmart is just riding the curve. Just my two cent's worth.
