On Wal-Mart's website, the movies will be available the same day the DVDs go on sale in stores. Rental prices range from 99 cents to 599 cents. Digital purchases are priced from $4.99 to $24.99.
Walmart.com general manager Steve Nave said the retailer is following its customers as they increasingly embrace digital movie rentals and purchases.
"We know customers are starting to shift their behavior, in terms of how they consume their media," Nave said, adding, "As as customers make that change, we don't want to lose that customer as they shift to digital."
Wal-Mart, long the nation's leading seller of DVDs, signaled its intent to double down on digital movie distribution in February 2010, when it spent a reported $100 million to acquire Vudu, a Silicon Valley start-up that was gradually being added to home entertainment devices.
