Here's how credit card payment works. When the iTunes account is bound to your credit card, it will deduct $1 to verify whether the credit card is correctly associated, but $1 will be automatically refunded.

however, the purchase is like this: if you make a purchase with a credit card, a message will be sent to your mailbox after the purchase, and a Receipt will be sent to your mailbox as soon as the settlement is made every month, in which the bill of this month is written and the deduction will be made at the same time.

there is another method that is the same as that I used. I don't have a credit card, so I bought a Gift Card in the United States, recharged my account, and deducted the fee from my account at the same time, and issued the bill at the end of the month (actually, every Monday).

I have tried to pay by credit card, which was just mentioned. But now I usually use Gift Card.

I hope I can help you. If you have any questions, you can ask or HI me. If you find a more appropriate answer, please adopt a more appropriate answer.
