To make four servings of Homemade Cashew Yogurt, you need 1 cup raw cashews, which costs anywhere from $3 to $6, or sometimes more, when purchased in the United States, depending on whether they are organic, and where you buy them. Buying them from bulk bins in the supermarket is the cheapest option. Store bought cashew yogurt is about $2.50 for a single-serve container. Plus, it is not widely available. I also find the texture of commercial cashew yogurt too thin for using it in place of yogurt for recipes that call for dairy yogurt.
