Don’t let “Out of Stock” be a dead end for your customers.
When you run out of inventory, you usually lose the customer. With Out of Stock Affiliate Redirect, you can save that sale by sending the customer to an external source (like Amazon, eBay, or a partner site) where they can still buy the item—and you can earn an affiliate commission.
This lightweight plugin adds a simple field to your WooCommerce “Inventory” tab. If the product stock reaches 0, the “Add to Cart” button disappears (standard WooCommerce behavior), and our plugin inserts a call-to-action button linking to your backup source.
<h4>Features</h4>
<ul>
<li>Simple Setup: Adds a URL field directly to the WooCommerce Product Data “Inventory” tab.</li>
<li>Automatic Trigger: The button only appears when the product status is “Out of Stock.”</li>
<li>Custom Button Text: Change “Buy on Amazon” to “Buy on eBay,” “Check Partner Stock,” or anything else per product.</li>
<li>Affiliate Friendly: Great for Amazon Associates or other affiliate programs to monetize out-of-stock traffic.</li>
<li>Theme Compatible: Uses standard WooCommerce hooks (<code>woocommerce_single_product_summary</code>) to display correctly on most themes.</li>
</ul>
<h4>How it Works</h4>
<ol>
<li>Edit a Product in WooCommerce.</li>
<li>Click the Inventory tab.</li>
<li>Enter a URL in the Alternative Buying URL field.</li>
<li>(Optional) Enter custom text for the button (Default is “Buy on Amazon”).</li>
<li>When your stock hits 0, the button appears automatically!</li>
</ol>

Allows users to point WordPress objects (posts, pages, custom post types) to a URL of their choosing, which is particularly useful for injecting non-WordPress content into loops. The object appears normally in any loop output, but visitors to the object will be redirected to the specified URL. The plugin also allows you to choose the type of redirect, either temporary (302), or permanent (301).
Through a filter, the External Permalinks Redux meta box can easily be added to custom post types. There is also a function available for use with WordPress’ <code>add_meta_box</code> function.
This plugin was originally written for use on WordPress.com VIP. It is inspired by and backwards-compatible with Mark Jaquith’s Page Links To plugin, meaning users can switch between plugins without risk of losing any existing external links.
This plugin is translation-ready.
