WooThemes - WooCommerce Catalog Visibility Options v2.5.0
Wait, what? Remove eCommerce functionality? It may sound strange but when you think about it, if you take out the cart, checkout process and 'buy now' buttons, WooCommerce is actually the perfect platform upon which to showcase a catalog of products which aren't currently for sale online. The added beauty of this solution is that when you do want to start selling, you can do so with the flick of a switch.
