I want to add a new price break down line to the WooCommerce breakdown page. I've looked at using these hooks which supposedly should allow me to post to the table.
woocommerce_review_order_after_cart_contents woocommerce_review_order_before_shipping woocommerce_review_order_before_cart_contents
However, if I echo a string as a test it always appears above the checkout table price break down.
Is there any way to add a new line item to the WooCommerce checkout table?
