Custom store

Hi, content egg can compare between almost every well known ecommerce store. But if I want to include my own store as one of them, is it possible? What I want is, I have a product comparison site with content egg and rehub installed. The content egg compares product from Amazon and Wallmart there. I sell some of the products which are available in those two. But my price is lower. I want to show visitors that my price is lower by comparing the product from Flipkart, Wallmart, and as well as my store. Is it possible somehow??
