Saving you $2,500 per year, one way or another

Wal-Mart's claim that is saves families $2,500 per year is supported, sort of. From the story:

BENTONVILLE, Ark. — Wal-Mart Stores Inc. needs to change its advertising to avoid suggesting its shoppers save an annual US$2,500 per family, the advertising industry's self-regulatory body said in a report Monday.
But the report accepted Wal-Mart's claim that its efficiency and size drive down consumer prices across the entire U.S. economy, generating that $2,500 savings regardless of where consumers shop.
The National Advertising Division of the Council of Better Business Bureaus singled out what it called implied claims in the retailer's ads that consumers who shop at Wal-Mart can realize that much in savings while people who shop elsewhere do not. Bentonville, Ark.-based Wal-Mart said in response it never meant to imply the savings were only for its shoppers.

TK: Wal-Mart doesn't want to say Americans can save just as much money at Target, but that's closer to the truth of the matter, I suppose.
