title: Hide price items for specific product categories in Woocommerce email notification
body: <p>I'm using WooCommerce 3.1.1 and I am trying to replace the "price amount" with some text for specific product categories in New order noification for customers and admin. </p>
  
  <p>I have almost tried everything but I am unable to locate the order item detail table for email notifications. </p>
  
  <p>This email looks like this for now: </p>
  
  <p><a href="https://i.stack.imgur.com/R4nrK.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/R4nrK.png" alt="Email"></a></p>
