In order to reserve a product, you will need to complete the purchase process. Adding items to the shopping basket without completing the purchasing process does not constitute a reservation.

Once you have added all the items you want to buy in the basket, the next step will be to process the order and make the payment. To do so, please follow the steps of the checkout process, filling out or verifying the information requested in each step. To complete your order, you must first enter your zip code to see delivery options. Then you must enter your delivery address details. Finally, make your payment.

During the purchasing process, you will be able to go back and modify the details of your order before making your payment.

If you have any questions during the purchase process, please contact our Customer Care to help you complete your order.
