WooCommerce Product Dependencies is a plugin designed for WordPress that allows users to control product access based on the ownership or purchase of other required products. This lightweight tool simplifies the process of managing product dependencies without the need for a full membership site. Users can create conditional access rules that enhance the shopping experience by ensuring customers meet specific criteria before purchasing certain items.

The plugin supports three types of dependencies: 'Ownership', where access is granted only to customers who have already purchased the required products; 'Purchase', which allows for purchasing dependent products only in combination with required items in the cart; and 'Either', which provides access through either ownership or purchase. This functionality is essential for businesses looking to create tailored shopping experiences and requires WooCommerce version 2.2 or higher.
