The thrifty, regular prices are for goods that you'd find in a standard grocery store bought with thrift in mind. No products contain transfats. Often the fruit and vegetables come from the farmers market and when the price is right, other items such as corn meal are local too. But these products make no claims of being organic or sustainably raised. In the older, pre-vegan recipes, the eggs and dairy have no claim to being hormone free, free range, or the like. That's one of the reasons that eating a plant-based diet makes so much sense if you are on a very tight budget.
