Wal-Mart, the nation's largest retailer, has lowered drug prices a third time. From the Associated Press: "Wal-Mart Stores Inc., the world’s largest retailer, announced Monday it would expand its discounted prescription drug program to offer 90-day supplies for $10 and add several women’s medications at a discount. It also said it would lower the price of more than 1,000 over-the-counter drugs."
The price reductions cover one-third of the company's over-the-counter stock.
