When looking for pricing information, consider the prices at production, import, wholesale, and retail. Some of this data may be difficult to find, and you may have to conduct primary research to gather the information you need.
Another way to find the retail price for a specific product is to visit a variety of stores and check the prices. Some of the larger organic stores in the US include Whole Foods and Trader Joe's. In Germany, two of the largest organic retailers are Denn's Biomarkt and Alnatura.
