The company plans to make on-demand music streaming available as part of its Prime service by June or July.
Wal-Mart has found a way to cash in on the feud between Amazon and the book publisher Hachette.
Amazon and Hachette, the publisher of popular authors including J.K Rowling, are fighting over digital book prices.
Amazon has reportedly blocked pre-orders for some upcoming releases, including Rowling’s "The Silkworm."
So, Wal-Mart jumped into action.
The world's largest retailer began offering nearly 400 Hachette titles for 40-percent off with delivery dates as soon as this week.
Barnes and Noble's web site is also offering discounts for Hachette books.
