title: Woocommerce - Remove "buy now" button from related products
body: <p><a href="http://www.happyhealthymarket.com/" rel="nofollow">Here</a> is my site. </p>
  
  <p>I used the following code to add a buy it now button to my product archives page:</p>
  
  <pre><code>/** Add buy it now to shop page **/
  
  add_action( 'woocommerce_after_shop_loop_item_title', 'woocommerce_template_loop_add_to_cart' );
  </code></pre>
  
  <p>Now the button shows up on my related products (See <a href="http://www.happyhealthymarket.com/product/worlds-first-bluetooth-smart-fork/" rel="nofollow">here</a>), but I only want it to show on the single product page and archive/category pages. </p>
  
  <p>Thanks for your help!</p>
