This holiday season, the hottest trend among retailers isn't found on a store shelf. It's taking place at the cash register.

The biggest retailers, from Best Buy to Toys R Us, are promising to match their competitors' prices. Generally customers just need to bring in an advertisement or printout to prove that the same item is available elsewhere at a lower price. In some cases, shoppers can come back with a receipt and get a refund for the difference if the price of an item they bought fell.

Best Buy Co. Inc., Target Inc., Walmart Stores Inc. and Sears Inc. offer price matching to customers all year round. But what's different now is that Best Buy and Target are matching online retailers such as Amazon.com for the first time. That's a big deal, because online prices tend to be lower than those at stores.

Shoppers will be able to save some extra money, but they're going to have to read a lot of fine print to do so.

"Price matching sounds good, but there are so many exclusions, it sometimes isn't as good as it sounds," said Edgar Dworsky, the founder of ConsumerWorld.org, which tracks deals for shoppers.

For instance, Target limits the number of online retailers that it will price match against to just five. Best Buy has selected 20, but only matched online prices from Nov. 1 to Nov. 17 and will start again from Nov. 27 to Dec. 24.

Toys R Us is offering price matching for the first time and will match only prices that customers find in other brick-and-mortar stores. Walmart also matches against in-store prices.

Toys R Us, Best Buy, Sears and Target say they will match prices found on their own websites. It's not uncommon for retailers to offer steeper discounts online than in their actual stores. (But Toys R Us says it won't match prices on its website if the item is marked as an "online-only price.")

Even the most experienced bargain hunters can get tripped up by all the rules. But shoppers can save some money if they're diligent.

Here are five ways to get the most out of price matching offers:

Know the policy • Generally, you can find a retailer's guidelines on its website. Bringing the hard copy with you will be helpful if you need to argue your case.

Show proof • Always bring the advertisement or the printed Web page for the item you want to price match. Walmart doesn't require this because it says cashiers have access to all local ads, but if there's any confusion, it's best to be prepared to make your case no matter where you shop.

The cashiers and customer representatives are always looking for a reason not to approve the transaction, Dworsky said.

Save receipts • Some retailers will give you money back if you see a lower price after you buy an item. Keep a hold of your receipts and, particularly for big-ticket items, continue to look for lower prices.

Best Buy will issue refunds until the end of January. Toys R Us lets you seek a refund up to seven days after buying an item. Sears customers can get a refund after 14 days. Target is letting customer's price match against brick-and-mortar retailers until Dec. 24 for any item bought after Nov. 1. You can only ask Target to match the price of an online retailer until Dec. 16.

Go straight to the customer service desk • Many retailers have hired cashiers specifically for the holiday rush, so the new employees may not be up-to-speed on the store's price-matching policy. Heather Wheeler, who runs savings website TheKrazyCouponLady.com, recommends handling the transaction at the customer service desk instead on the cashier.

Look beyond retailers • EBay Inc.'s payment processer, PayPal, promises to match a lower price if you've already made a purchase using the service. That includes airline tickets. PayPal will give you back up to $1,000 for all purchases made until Dec. 31.

You should also ask your credit card company to see if it offers price matching. It's rare, but there are a few cards that do. Citi just launched a program, Citi Price Rewind, that registers your purchases made on the Citi credit card online and will send you a check for the difference if it finds a lower price from an online retailer.

The program is aimed at pricier purchases: It will only issue a discount if the price difference is $25 or more. Citi will give you the amount up to $250 for each item, and up to $1,000 a year. Of course, you're going to need pay your credit card bill in full and not incur interest charges to truly make this a deal. —

Sorting through price matching

How it works • Merchants promise to match a competitor's price if you bring in an advertisement or printout that proves that a rival is selling an item at a cheaper price.

Confusing policies • There are a lot of exclusions. Consumers should read the terms and print the policy from a store's website so that it's readily available when they request a price match.
