Shipping cost depends on the volume of your order. Except in the case of a prior arrangement, all deliveries will be made by DHL for Europe and Australia, UPS or FedEx for North America . Express delivery for receipt within 48 hours can be arranged on demand.
The shipping cost indicated is only a rough estimation (high estimation). Real shipping cost is only known once the parcel is ready, but it's usually between 20 and 25% of the total of your order.
If the final shipping cost is eventually less expensive than the one estimated, we simply deduce it from your initial payment on Paypal. If it's more expensive, we confirm your initial payment as it is and send you another money request for the remaining.
