# Price comparison based on feeds

If your feeds have EAN field for all products from different merchants, you can make price comparison using [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 shortcode to body of post to show price comparison list or use special Content Egg product layouts from compatible themes.
