WooCommerce Give Products
Give products to a customer, free of charge
Give products to a user, with a free of charge order, without going through the entire checkout process. This is the plugin we use ourselves on WooCommerce.com, to gift products to customers.
The intuitive interface provided by WooCommerce Give Products makes this process a breeze. Simply select the customer you’d like to give products to, select the products you’d like to give and click the “Give Product(s)” button. That’s all there is to it!
