   global $woocommerce;
   $cw_discount = 0;
   foreach ( $woocommerce->cart->get_cart() as $cw_cart_key => $values) {
       $_product = $values['data'];
       if ( $_product->is_on_sale() ) {
            $regular_price = $_product->get_regular_price();
            $sale_price = $_product->get_sale_price();
            $discount = ($regular_price - $sale_price) * $values['quantity'];
            $cw_discount += $discount;
        }
   }
   if ( $cw_discount > 0 ) {
        beans_open_markup_e('discount_table_tr_1', 'tr', array( 'class' => 'cart-discount' ) );
      beans_open_markup_e( 'discount_table_th_1', 'th');
               _e( 'Secure', 'woocommerce' );
     beans_close_markup_e( 'discount_table_th_1', 'th');
