Hi Big Z,
Where I live, at the local grocery stores, there is a natural foods section. Call ahead to see if your local supermarket has one. Most do. Also ask if they have that particular product. If you live in a bigger city, you probably have a whole store that has natural foods. We have one in Fargo, ND, a city of 90,000 that's been around for over 30 years.
Walmart usually only has the more popular natural/organic items.
