--- What does Pricezilla do? --- Pricezilla is a browser add-on that helps you shop at the lowest prices. When you view a product online, Pricezilla lets you know if it detects a better price for that product and presents you with a list of stores where you can shop and save some money at the same time. We'll also show you similar products which are available at a lower price, great deals and offers from trusted online merchants. --- Here's how it works --- Pricezilla analyzes the product page that you are currently viewing, searches through its database of online shops and shows you a list of shops that offer that same product, only for a lower price.
