The plugin adds a custom WooCommerce Coming Soon page for classic themes. 
The plugin uses the new <a href="https://woocommerce.com/document/configuring-woocommerce-settings/coming-soon-mode/" rel="nofollow ugc">WooCommerce Coming Soon mode introduced in WooCommerce 9.1</a>.
You can create 2 types of templates in your theme’s folder: 
* <code>store-coming-soon.php</code> – for Coming soon mode only 
* <code>site-coming-soon.php</code> – for Coming soon and Apply to store pages only mode
Or copy the ready-made template(s) from the subfolder <code>templates</code> of this plugin and place it into yours site theme folder.
IMPORTANT: for WooCommerce version 9.5.1 and higher you have to use filter <code>wpwc_classic_coming_soon_store_only_content_id</code> for <code>Coming soon -> Apply to store pages only</code> mode.
For example, add this PHP code snippet in <code>functions.php</code> of your theme:
<pre><code> add_filter( 'wpwc_classic_coming_soon_store_only_content_id', function () {
 return 72663;
 } );
</code></pre>
where <code>72663</code> is page ID which content will be used for <code>Coming soon -> Apply to store pages only</code> mode.
<h4>Requirements</h4>

Sometimes your products are not quiet ready but you still wish to show your customers what you will be selling next. This small extension enables you to do just that by displaying a message to the customers “Coming Soon”.
This only works if the stock status is set to “Out of Stock” or the stock level of the product is ZERO.
You can if you wish use a custom message that is unique per product. They don’t all have to say the same.
