The page keeps saying that my order is being processed.
Your purchase is usually authorised immediately.
However, there are rare occasions when the authorisation process can take up to four hours. If the purchase does not go through after four hours, please try to purchase again.
If you are using a payment method that redirects to an external page (such as PayPal), you will be redirected back to the store after confirming your purchase. The authorisation process can therefore take 60 seconds. To avoid potential problems, do not click the back button of your browser or close the browser window.
