Another day, another social shopping offering (this time a comparison engine). PriceSpider.com, backed by leading Microsoft National Systems Integrator Neudesic, announced the launch of its price comparison web site to help consumers (what else) save time and money. PriceSpider.com is billing itself as the latest in social networking and ground-breaking web-crawling technology. Let's look at how it works.

Traditional comparison web sites only post pricing and availability periodically for a limited group of retailers. The advantage of PriceSpider.com is that it is an active search engine using technology that continuously scans for pricing and product information. The search spans hundreds of online retailers in real-time to provide consumers with the true lowest price available on the web. PriceSpider also enables users to create a personal network to share their product lists with others and features the ability to communicate with their personal network to track and share product and pricing information.
