You may receive multiple SMS or app notifications because Pre-Order items(s) or orders that include Pre-Order item (s) often involve more than one payment stage. This may occur for the following reasons:

i) Pre-authorization notification
When you place an order that includes Pre-Order item(s), a temporary authorization may be placed on your card to confirm payment availability. Your bank or payment app may notify you of this authorization, even though no money has been charged at this stage.

ii) Final Payment Notification
Once the Pre-Order item(s) is ready and the payment is successfully processed, you may receive another notification confirming that the final payment has been completed

iii) Security or bank alerts
Banks and payment providers may send additional notifications as part of their security and fraud‑prevention measures

iv) Payment updates or adjustments
In some cases, you may receive notifications relating to payment status updates, authorization release, or refunds.
Each notification reflects a different stage of the payment process and does not necessarily mean that you have been charged multiple times.
