  <pre><code>/*
  Disable Variable Product Price Range completely:
  */
  
  add_filter( 'woocommerce_variable_sale_price_html','my_remove_variation_price', 10, 2 );
  add_filter( 'woocommerce_variable_price_html', 'my_remove_variation_price', 10, 2 );
  
  function my_remove_variation_price( $price ) {
  $price = '';
  return $price;
