Price Comparison Sites
Many price comparison websites crawl the Internet and collect pricing data from various retailers. This information often is presented to consumers in an easy-to-read format, usually listing the store with the cheapest price first. See the resources section for links to several of the more popular price comparison sites.
Mobile Price Comparison
Smartphone applications, such as RedLaser for the iPhone, use a camera to scan product bar codes to identify products and compare prices with online stores. Services such as FruCall allow consumers to send a text message with a UPC number to the service and receive a reply with the cheapest price online and the store offering it.
Correct Product Identification
When comparing prices for Rock Band 2 for the Nintendo Wii, be sure to search for the correct version. The game is offered as a complete package with musical instrument controllers and also as just the software disc. It's also important to make sure prices are for the Wii version, as Rock Band 2 is also available for the Xbox 360 and Playstation 3.
