Wal-Mart adds one million items to boost online sales

Wal-Mart Stores (WMT), the bargain retailer known for its massive big-box stores, is using its heft to boost online sales to better compete with the likes of Amazon.com (AMZN) and eBay.

Wal-Mart announced on Monday that it has begun selling one million more items through its website, walmart.com. Wal-mart Marketplace offers products in categories such as sporting goods, apparel, baby, home, luggage and toys. Among the retailers included are CSN Stores, ebags and ProTeam, with more to be added.

The move will give Wal-Mart better footing to compete with Amazon.com and Apple (AAPL), which, according to analysts, has displaced Wal-Mart as the largest seller of music.
