What's up with Wal-Mart's US sales slump?

Wal-Mart, stung by an embarrassingly long sales slump, is finally ready to do something about it. On Monday, Wal-Mart announced it is bringing back thousands of products that were unceremoniously dumped from stores, saying it is ready to roll up its sleeves to win the lowest-price battle with its rivals.

To show its resolve, the world's largest retailer is adding a new tagline to its slogan "Save Money. Live Better." That tagline, which will now appear throughout Wal-Mart stores is "Low prices. Every day. On everything."

"What our customers are telling us is that they want the right products in a one-stop shop at the lowest prices. We're trying to reestablish that message," said Duncan Mac Naughton, Wal-Mart's chief merchandising officer.
