We will never charge you multiple times for the same order, but if something goes wrong and the same order is placed multiple times then you will be charged for each. This could be because you have accidentally clicked the order button multiple times when going through the checkout. If this happens you will receive a separate order confirmation email for each order that has been processed. Please contact our customer support team for help cancelling the additional orders that were placed in error. If you have not received multiple order confirmation emails, then it may be that your bank has both released funds to us and reserved funds in your account, therefore showing two transactions. In this case the reserved funds will be released back into your account shortly.
