You’re shopping and seeing an item you like, but you wonder if it costs less elsewhere. With RedLaser, a FREE app for both iPhone and Android phones, simply point the phone’s camera at the product bar code. The app scans it and searches the Web to find the best price. For phones with Google Android, such as the Motorola Droid, try a similar app called ShopSavvy (FREE!), which is also available for the iPhone.
