If you prefer to pay Bank Transfer, please send us an email asking for our bank account number. When placing an order by Paypal also include an email in addition to your shipping address. We will use that email to send you the tracking number once the order is shipped. With the tracking number you will be able to follow here, the state of the delivery of your order. We use the Portuguese Postal Office which refers a delivery of 3 working days to Europe and 5 working days to the rest of the World. However when dispatching to outside EU, delivery can take longer if it stops at the customs. Also note that a signature is required when the order is delivered so make sure that this is possible at the shipping address. If by any reason you are not satisfied with your order you can return it during the period of 30 days following the delivery of the order at your address but you are responsible for return postage costs. When we receive a returned product we will send you the amount paid by Paypal or Bank Transfer.
