In his prepared remarks, Agwunobi will mention that more than 100 of Wal-Mart's $4 prescriptions ( walmart.com/pharmacy )are used to treat heart disease and diabetes. He will also add:

"While $1 billion in savings is an astonishing achievement, the real savings to America -- and its health care system -- are even larger. That's because many of our competitors have also lowered their prices. $4 prescriptions now represent approximately 40 percent of all filled prescriptions at Wal-Mart. Nearly 30 percent of $4 prescriptions are filled without insurance -- significantly higher than the 10 percent industry trend. But more importantly, this program has meant that people can now take the drugs that were prescribed to them. They no longer need to cut pills in half or not take the drugs at all."

Wal-Mart, Sam's Club and Neighborhood Market customers in Texas, Florida, North Carolina, Georgia and Missouri top the savings list respectively, each with more than $40 million in prescription drug savings. A breakdown by state is available at livebetterindex.com/health.html.

Wal-Mart's $4 prescription program, which can be accessed at walmart.com/pharmacy covers most commonly treated medical conditions and continues to drive down health care costs for families. For further information on the program, customers can call 1-800-WALMART or visit their area Wal-Mart, Neighborhood Market or Sam's Club to discuss the program with their pharmacist.
