We discuss the basic theory of price indices. These form the basis for the Consumer Price Index in the United States. We note situations which can lead to non-robustness and volatility in several different price indices. An experiment to replace survey-based data with point of sales scanner data is being carried out. We visually explore the scanner data and conclude that certain aspects of scanner data can lead to non-robustness of commonly used price indices.
