Thanks to YITH WooCommerce Brands Add-on, you can create brands you can link to the products in your shop. Products can be filtered based on the selected brand and this will make it easier for users to find products they might be interested in.
This integration allows creating custom discount rules for all the products associated with a specific brand and offering advantageous benefits to the users willing to purchase them.
After installing and activating both plugins, you will be able to include or exclude selected brands from the rule you are creating through the options Apply to and Apply adjustment to.
For further details about YITH WooCommerce Brands Add-on settings, please refer to the official documentation.
