The order you placed may have been cancelled for a few reasons.  If you purchased one item with us, it was likely cancelled because it was out of stock when it came time to process the order.  If the entire order was cancelled it may have been because all purchases made online with us go through a fraud check system to verify cardholder information.  If the information did not verify properly the entire order might be cancelled.  Your financial institution may be able to provide additional information.
