First, duplicate this sample product page by clicking on Product Page > ••• > Duplicate. We recommend duplicating the product page as many times as needed, to align with the products you'd like to showcase in your Shop. Then, customize accordingly. 

Lastly, go back to your Shop page, and ensure you've successfully linked to each additional product page you've created. It's easy peasy!

Of course, if you don't need a Shop at all, simply hide the Shop link from any navigation menus throughout your design. That way, you can develop a Shop later on, while keeping the page designs handy, behind-the-scenes of your Showit dashboard.
