Hi, I'm , an Independent advisor and I can surely help you.

Don't worry we will work on this together. May I know what's the exact error when you're trying to purchase?

The other way is buying a gift card from a retailer, redeem it in your account and then subscribe the Xbox Live Gold using the money in your Microsoft Account balance.

Yes I understand that it will add on to my existing microsoft credit. The question is that the gift cards you redeem through rewards have a 90 day expiry date where you have to spend that money within that time. The money I have in my account is through bought gift cards and as so has no expiry date to use the money by. I just want to know if I redeem gift cards through microsoft rewards, when I buy a game it will use the gift card money with the expiry date first and not the money i already have in my account. If that makes sense. Thanks.

The £10 must be either on a card that says "Xbox Gift Card £10" or you must purchase an Xbox digital gift card code on Amazon for £10 that you redeem here:

You can't redeem Amazon gift cards or currency in Amazon accounts for currency in your Microsoft/Xbox account - you must buy an Xbox Gift Card (or code) with that money on it.
