The out of stock notice feature for WooCommerce is included in our free plug-in, and you can use it to improve the quality of life of your customers. By displaying an out-of-stock notice on your shop page, you prevent the customer from opening a product page and find out that it is out-of-stock, this will save your customer the frustration of going back, and reduces the friction before your customer find a product of interest.

However, with the out of stock notice for WooCommerce, you can also be creative, and use it to launch your new products before making them available. I have used this simple feature to build up the hype, for a fashion shop. A simple and trivial lead magnet to populate your newsletter list quickly and with quality subscribers, that you know are interested in a specific product line.
