title: WooCommerce inquiry if no price available
body: <p>I'm helping a good friend setting up a WooCommerce shop. Since the shop is going to be bigger and the products are pretty variable and customizable we are not able to provide/configure all prizes from the beginning. </p>
  
  <p>However we would like all products to be in the shop and ad an inquiry lead form in case no price is available. </p>
  
  <p>Since I never programmed with WooCommerce I was wondering that is the right hook to implement such an functionality?</p>
