How to order Xbox credit from Amazon?

There's no order but how do I order the credit?

I want to order on my cell phone, maybe that's important.

I see no mistake there

Would still order credit directly from MS: https://www.microsoft.com/...ards?rtc=1

I don't recommend Amazon but MMOGA.com

there you get a code for cheaper price (-2 euro to -3 euro

In the picture there's a yellow rectangle on the Add to cart…

Or did I misunderstand the question?

Thanks kanna 😊

Yes, but there should actually be a rectangle on which you can buy now

But you can put it in the shopping cart and then go to the checkout.
