remove text/table entry 'shipping & handling' everywhere in magento

Question

I was able to remove it from the checkout page. But it is still in the my order review page as well as the print version of the order. So far I didn't find it anywhere else. But is there a way to not show it in the frontend?

I changed Shipping.php and totals.phtml (all of them) but no matter what I commented or tried had any influence on it. Where do I have to change this?
