Checkout Add-Ons for WooCommerce

If an individual product has an addon (we use woocommerce product addons plugin), at checkout, it would be great if we could also add these at checkout. Even better would be if we could allow the ability to add them with a discount.

For instance, if a customer can add “warranty” when on a product page, if they don’t, at checkout, it prompts them again at a reduced rate.
