"International orders are handled as follows:
The order is placed by the customer using the MouseMemories.Com shopping cart.
International shipping MUST be selected at checkout and a temporary shipping charge will be applied at the time of purchase.
The ordered items are pulled at the Order Fulfillment Center and the package is weighed. We determine the actual postage for the package weight using the United States Postal Service International Calculator.
MouseMemories will then refund the amount overpaid between the temporary shipping charged on the order and the actual United States Postal Service Airmail shipping costs. On those very rare occasions in which the actual United States Postal Service Airmail shipping costs turn out to be higher than the temporary shipping charged on the order, then the additional amount will be charged to the guest's account.
All duties or import taxes that may be assessed for international orders are the responsibility of the guest (customer).
We can not mark "gift" on the custom forms to avoid customs duty as this is a federal offense for which MouseMemories will be held liable. Please do not request this of us. "
