// Order total in default currency without fees
$order_total = $this->getOrderTotal(true, Cart::BOTH_WITHOUT_SHIPPING, $product_list);
Добавить это
//Recalcul total pour panier et livraison gratuite
$listeDiscounts = $this->getCartRules();
$total_discounts = 0;
if (is_array($listeDiscounts)) {
if (isset($listeDiscounts[0]['value_real']))
$total_discounts = $listeDiscounts[0]['value_real'];
}
$price_to_apply_shipment = floatval($order_total) - floatval($total_discounts);
Заменить
//$check_delivery_price_by_price = Carrier::checkDeliveryPriceByPrice($row['id_carrier'], $total_order, (int)$id_zone, (int)$this->id_currency);
by
$check_delivery_price_by_price = Carrier::checkDeliveryPriceByPrice($row['id_carrier'], $price_to_apply_shipment, (int)$id_zone, (int)$this->id_currency);
И
//$shipping_cost += $carrier->getDeliveryPriceByPrice($the_total_price, $id_zone, (int)$this->id_currency);
By
$shipping_cost += $carrier->getDeliveryPriceByPrice($price_to_apply_shipment, $id_zone, (int)$this->id_currency);
