Crowdsourcing: What's the Price of Milk, Eggs, Cereal...?

Our next "crowdsourcing" project sets out to look at how the prices of a pre-determined basket of goods differ throughout the New York area. We plan to ask listeners to investigate the prices in their local stores, or stores in any other neighborhood, to get a snapshot of prices. We're still trying to select the three goods, and we're inviting listeners to collaborate with us at this early stage. What are the most representative products? Milk, eggs, flour, breakfast cereal? Let us know on the air and in the comments section.
