Unfortunately, it is not possible to add extra items to an order after purchase. You approve an amount when placing the order, which we cannot exceed for security reasons. Instead, you can make two orders. When placing order number two, please write a message to us during the purchasing process in the box marked 'comments'. Let us know that you would like both orders to be sent together. In writing this message in the comments box, please note the order number of the first order. We will strive to have them sent together, but it cannot be guaranteed as the first order may have already been packed.
