You cannot personally change your order after approving purchase. However, our customer service can change or remove items from your order as long as the order has not yet been processed by our warehouse. Contact us here and we'll be happy to help. Please note that we do our best to process and ship all orders as quickly as possible, and there is only a small window in which we can make changes to an order. This means we may not always be able to help you, even if you contacted us right away.
