Don't be fooled by discounts off the 'list price'

You're in the market for a TV. The one you want is $100 off the list price at one store and 20 percent off the list price at another.

Which one is the better deal?

The only way to tell is to compare the final price -- what you'll pay to buy that TV.

This is the time of year when stores really hype their prices to get your business as sales move merchandise. But in some cases, the list prices or reference prices listed in the ads or marked on the price tags don't really exist.

That's against the law, but it happens.

To get the best deal, you need to comparison shop. Consumer Reports' Tod Marks says great deals are right at your fingertips.

"There are free apps you can download to your smart phone to do price comparisons," Marks says. "They can let you know which store has the item you want at the lowest price."

Consumer Reports says two worthwhile apps are PriceGrabber and SnapTell. They let you type in the product's name or scan bar codes to find the best price. A little homework can save you a lot of money.
