The Federal Trade Commission and 9 states want to stop the deal that would combine the country's two largest grocery store chains. The companies say they have to merge to compete with Walmart.

"Shoppers will have fewer choices and less competition, and, without a competitive marketplace, they will pay higher prices at the grocery store," Washington state attorney general Bob Ferguson said.

America's two largest supermarket chains have struck a $25 billion deal to combine. Now the FTC is about to decide whether it will block or allow it, and under what conditions.
