The Retail Milk Price is a milk price series that is collected by the Market Administrator offices surveying one outlet each of the largest food store chain, the second largest food store chain, and the largest dairy/convenience store chain in the selected city or metropolitan area. The survey is conducted on one day between the first and tenth of each month, excluding Fridays and weekends. The price obtained is for the most common brand, based on shelf space, and does not represent a temporary special price, or one that is dependent on the purchase of other food items or the use of a cents-off coupon. The determination of the largest and second largest food store chain is based on estimated sales of fluid milk products in the metropolitan area. Currently, prices are collected for conventional whole milk and conventional reduced fat (2%) milk, sold in gallon containers, and organic whole milk and organic reduced fat (2%) milk, sold in half-gallon containers.
