Yes, I tried it and it's good, but it depends upon what API you use. Shopzilla pays good comparing to shopping.com. I have a website which I want to sell, domain name plus script, and which uses shopzilla API, google ads and banners. It's a very powerful website, both front-end and back-end. Even the products come from the API, they are easily manageable using the admin/back-end. The website is www.shopquiz.com . I am selling it due to the fact I have not much time to handle it and promote it over the internet. If you are interested PM or email me at the contact email you can see on the site.
