# Price comparison based on feeds

If your feeds include an EAN field for all products from different merchants, you can build a price comparison using the [Autoblog](https://ce-docs.keywordrush.com/set-up-products/autoblogging) or [Fill](https://ce-docs.keywordrush.com/set-up-products/fill-tool) feature. All products with the same EAN will be [merged together](https://ce-docs.keywordrush.com/set-up-products/price-comparison-websites#search-by-ean).

Don’t forget to add a shortcode to the body of your post to show the price comparison list, or use the special Content Egg product layouts from compatible themes.

You can use the [Fill tool](https://ce-docs.keywordrush.com/set-up-products/fill-tool) if you want to add offers to your existing products.
