If I want to order an Xbox voucher on Amazon, then it is there Please note. Why can't I order?

There's then: Please set the default address here to buy this product. It has been removed from your cart. All package discounts for this product can't be considered at the time of purchase. What shoud that? How can I order now, I have tried it all the time even rewrite address but it DOES NOT!

With what do you pay?

because I read a similar question months ago and there was the problem that you could not pay with an amazon voucher. You have to pay with your bank account

Voucher and I can't pay with bank account so not at the moment!

Then it will not work
