How can I purchase a xbox gift card with the gift card I have on my account

How can I access the gift card? In my order history when I purchased the gift card it says i got "miscellaneous credit" of $1.25 added to my microsoft account, not a gift card.

So why is it that you are not allowed to gift shark cards. You can gift anything else but shark Cards. I have unused credit in my microsoft account but the only thing played is gta v and i want to buy shark cards for that game. But I can only purchase
it for my own account. I cannot transfer it nor can I buy a gift card with my credit even tho I purchased the gift cards myself to put on the account. And now im being told GTA V SHARK CARDS CANNOT BE GIFTED !!! Why !!??!?! Please help

So, you just restated my problem as the solution. Awesome. I don't know anyone with a 360, and do not have a credit card. I can use my microsoft account balance drafted from the gift card to purchase things from the microsoft store, but not the xbox store
on the xbox website, even though it is an xbox gift card, and not a "microsoft store" gift card.

I see. You can try purchasing a gift card from this link, https://www.microsoft.com/en-us/p/xbox-gift-car....

Once you have the gift card, redeem the code on your account then you can use the account credit to purchase the subscription.

Gift cards cannot be used to purchase gift cards. The Microsoft account balance is essentially the same as a gift card since funds typically come from Xbox gift cards.
