We reserve the right at any time after receipt of the order to accept or decline the order, or any portion thereof, in our sole discretion, even after the Customer receives an order confirmation or after the credit card has been authorized. If the credit card has already been authorized for the purchase and the order is cancelled, we will issue a credit to the original method of payment. 

Please note that any orders that have already been packed or shipped cannot be cancelled.
