Output
When a customer adds the T-shirt with a logo to their cart, another product (a Polo) will automatically be added to their cart for free during the checkout process. If the customer removes the T-shirt with a logo from their cart, the free Polo product will also be removed from the cart page.
Similarly, you can also automatically add a product to your WooCommerce cart in 6 different scenarios such as based on cart total, product tags, excluding Buy One Get One offers for expensive items, product categories, etc.
