How to create Products page like on demonstration site.

Hi there,
Maybe my question will be stupid a little bit. But I can’t understand how to create Product page like on demonstration site. I'm new in Drupal.
I've created a view with products, but I can’t add button “Add to compare list”. Can some one help me and explain how to do that? I’ve spent three days with no result.
Sorry for bad English.

Thank you.
