MapsAndGlobesPlus.com endeavors to expedite all orders to customers as quickly as possible. In the event you find that you need to cancel an order, change an item in an order, or change the shipping address, please call us at 1-800-791-2946. Generally we cannot cancel an order once it has shipped from the manufacturer. However, the sooner you call the better our chance of catching the order in time. If we are unable to make the change before the order is processed and shipped, you may need to return the item. Please see our return policy for details.
