4. 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.
"(Those staffers are) trained a little more and are more knowledgeable," says Wheeler.
5. LOOK BEYOND RETAILERS
You can also price match depending on how you pay. 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 match the prices of retailers that don't let customers use PayPal, however. Just fill out a form and upload a receipt when you find a lower price. 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 for its credit card holders. Called the Citi Price Rewind program, it promises to do the work for you. Register your purchases made on the Citi credit card online and it 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.
