title: How to add suffix text to price in WooCommerce cart and checkout page?
body: <p>I need to add a text mention after prices (sub-total, total...) displayed in my cart page and checkout page.</p>
  
  <p>I know how to do that on single page and shop page but not on the other pages. The only thing I found is this code, but it does not work.</p>
  
  <pre><code>add_filter( 'woocommerce_get_price_html', 'custom_price_message' );
  function custom_price_message( $price ) {
    $text = 'lorem';
    return $price . $text;
  }
  </code></pre>
