WooCommerce already makes it easy to bring your store online and sell all kinds of digital and physical products. You can also use it to link to affiliate products to make money by selling other people’s products. Thanks to the External Variations WooCommerce Plugin, you can use variable product features for external products.
This plugin lets you create external variable products and set a different URL for each variation. It is designed to work with any WooCommerce theme. Burnhambox is the developer behind this handy script.
