Notes
During the card binding process, Amazon may initiate a small pre-authorization charge (approximately USD 1) to verify the validity of the card. This amount will be automatically refunded.
It is recommended to enter the correct billing address associated with your credit card to reduce the risk of verification failure or payment interception.
