My own Shopzilla site

Catalogue API provides advanced publishers with intuitive access to BizRate’s inventory of catalogued products and merchant offers through a query-based web service accepting various parameters, allowing publishers to filter based on their website’s shopping content needs. Based on these publisher-supplied parameters, customised BizRate shopping content is returned within an XML response.

The API will enable you to dynamically retrieve product results from the BizRate catalogue which means no manual updating. Once installed, you can sit back and relax as the data is called automatically.
