In early 2004, the U.S. government initiated the Medicare Drug Discount Card Program (MDDCP), which allowed card subscribers to obtain discounts on prescription drugs.

A large panel of pharmacy-level price data collected from this website indicates that price dispersion across cards persisted throughout the program.
