I clicked on this site and I do not know what to do anymore, ask for help

I do not understand what I should do now or click something

You must enter a bank account or credit card.

Do you have to? Because I have already charged 10 euro with a coupon

Yes, you have to anyway. You can pay with the credit or a voucher, a bank account or credit card you still need in the Amazon account.

Did it, but unfortunately not, but thanks in advance.

You have to click somewhere, what should be your default address. Do you have more in your account? Otherwise, write the best Amazon support. They react i.d.R. Fast and can help you more exactly.
