There are typically two reasons why an order doesn't show in a customers' account right after an order is placed.
1. There was a delay in our system:
An order confirmation email will be sent to you within a few minutes to confirm that your purchase has been taken into account.
*Be sure to check all your mailboxes associated with the email address on the order. Sometimes order confirmations are sent to spam.*
2. Your bank is in the process of authenticating the order:
Once an order is submitted, the validation of your order is sent to your bank for approval. This process can cause a bit of a delay for the order to finalize and show in your account.
