NEW YORK - Forget style, quality and customer service. This holiday season, all that matters is price.

A week before Halloween and two full months before Christmas, stores are desperately trying to outdo each other in hopes of drawing in customers worn down by the economy.

Wal-Mart, the biggest store in the nation, joined the price wars Monday by announcing that it would give gift cards to shoppers if they buy something there and find it somewhere else cheaper.

Staples and Bed Bath & Beyond have already said they will match the lowest prices of Amazon.com and other big Internet retailers. Sears is going a step further, offering to beat a competitor's best price by 10 percent.

"The days of marketing the stuff in your store because it was a hot brand are over," says Dave Ratner, owner of Dave's Soda & Pet City, a Massachusetts pet food and supplies chain.

For the holidays, Ratner plans to offer 20 percent off pet accessories if customers buy a bag of dog food. Customers, he says, just want a deal.

Almost four years after the onset of the Great Recession, they've learned to expect one too. In better times, retailers could afford to keep prices higher and use promises of higher quality and better service to lure people into stores.

Those days are over. In a recent poll of 1,000 shoppers by America's Research Group, 78 percent said they were more driven by sales than they were a year ago. During the financial meltdown in 2008, that figure was only 68 percent.

Wal-Mart last year went back to its "everyday low prices" roots, a bedrock philosophy of founder Sam Walton, rather than slashing prices only on certain items to draw in customers. Now everyday low prices might not be low enough.

So it's trying something it is calling the Christmas Price Guarantee. It works this way: If you buy something at Wal-Mart from Nov. 1 to Dec. 25 and find the identical product elsewhere for less, you get a gift card in the amount of the difference.

The deal excludes online prices and some categories of merchandise - groceries, live plants, tobacco, prescription drugs and wireless devices that require a service agreement. But it is good even if weeks pass between your purchase and spotting the better deal. And it applies even to big items like TVs, for which prices can drop steeply as Christmas approaches.

Duncan MacNaughton, chief merchandising officer for Wal-Mart's U.S. stores, told reporters Monday that he has noticed "much more promotional intensity and gimmicks" among competitors.

"This gives customers peace of mind that we are an advocate for them," he said.
