Xbox gold discounts not appearing on my childs account

Thanks for this. How do I add gold to his account?

The gold discounts will only apply to the account that purchased gold, or Ultimate in this case. So your account would be the only one who could take advantage of those discounts. The only options would be to either purchase them on your account and share
them with him, or add gold to his account so he can purchase them.

You would need to set the console as your Home console https://support.xbox.com/en-US/games/game-setup/my-home-xbox

This is not the case. My xbox is set up as my home console but my child cannot purchase games or extensions at the gold discounted price. I also cannot set up a gold account for my child with the current offer in Australia

That would of just been a random discount.

Can't ever remember there being a discount on xbox live gold based on gamerscore.

offers usually appear on your dashboard if your a silver account.

Other than that there are plenty of online stores that sell xbox live at a discount like electronicfirst.com

This is so annoying. The child accounts are not allowed to buy backward compatible games through the web! The only way is through the 360 console, but not the new xbox one! My child has got credit to spend and gold subscription, but how can he make use of
it and get the discounts he is entitled to for xbox 360 games? Buying xbox 360 is not an option.

Thanks
