If you can't be charged for an order - for instance, your credit card expired - we would send you an email when we next try to charge you to let you know the charge was unsuccessful. From that point, you have 24 hours to update your credit card information so that, the next time we try to charge you, the charge will go through. We will try to charge you about three more times over that 24-hour period, before canceling the order, so, as long as you resolve the credit card issue by the deadline mentioned in the email we send, you'll be golden!
