Refill: Checking in on Wal-Mart's discount drug programs

Last year, I wrote about the new discounted generic drug program introduced by Wal-Mart. The original program provided $4 prescriptions for a 30-day supply of about 300 drugs. At the time, Wal-Mart had tested the program in Florida and then expanded it nationwide. Other national drugstore chains and regional grocery store chains responded by offering their own discounted drug programs. Some retailers, such as Meijer and Publix, began offering free prescriptions for selected drugs. The winners of this pricing competition were the shoppers who took advantage of these programs.
