Upon receiving your order, our billing agent ASOS Transaction Services Australia Pty, carries out a standard pre-authorisation check on your credit or debit card to ensure there are sufficient funds to fulfil the transaction. Goods will not be dispatched until this pre-authorisation check has been completed. Your card will be debited once your payment has been approved.
If your card is not authorised, your card will not be debited, and we'll email to let you know your bank or card issuer wouldn't authorise the payment.
Please remember that even if a payment is not authorised, some card issuers may still reserve the money, meaning you can't use it for a short period.
