The main feature of the Camelizer is to provide price history charts inside Firefox when browsing products at Amazon. This lets you decide if the current price is good or not, based on historical data. You can also tell us how much you would like to pay for a product, and we will email you when the price drops! This add-on uses camelcamelcamel.com to provide some neat features at Amazon.com. To use the Camelizer: Visit an Amazon product page and click the Camel icon that appears in your address bar. Supports Amazon United States, Canada, (most of) Europe, Australia.
