This Christmas more and more shoppers are using their smart phones to help them save money while holiday shopping.
While comparison shopping can be time consuming, mobile apps such as RedLaser allows shoppers to check prices at multiple stores.
RedLaser allows shoppers to check prices at one store, while standing in another.
The app works by snapping a photo of an item's barcode. RedLaser then finds the item and scans other stores Web sites.
In addition to the online price, the app can show where the item can be found locally and how much those local stores are selling it for.
Amazon also has a price matching app, but it compares prices only with the Amazon price.
The RedLaser app is free and available for Android phones, iDevices and Windows phone.
