RedLaser — don't go Christmas shopping without this

RedLaser ($1.99) is currently one of the top-selling apps, and for good reason: It's a great aid to shopping. The concept is very simple — the app uses your iPhone's camera to scan a barcode, and then the app does an online product search to find the lowest price among hundreds of thousands of retailers. Maybe you're in a mall and you scan an item and find that a different store in the same mall has it for a lower price. Features include the ability to limit your search to lower prices in nearby stores, e-mail a results list, e-mail a barcode, and a favorites feature for keeping a wish list of products.
