Can I buy shadowlands with gold? If so how? Im pretty sure ive seen somewhere where u can put it on your blizzard balance but i dont know how?
If you learn something with your question it’s never stupid 
And yes, you can, use gold to add bnet balance to your account and use the balance to purchase SL
You do this by buying a wow token from the auction house.
But you must be from NA. I am from Europe and cant get bnet balance
Oh ok ty Unian if I just buy a token from the ah it automatically goes to my balance right?
Yes you can get gold in game, buy some wow tokens, then convert into bnet bucks. Then buy shadowlands with said Bnet bucks.
You’ll have two options, to add a month of gametime to your account or to add the balance, just pick balance and you’re good to go.
You’re given the option of putting it towards your Blizzard balance or adding game-time. Choose the blizzard balance route. Then, when you go to purchase the expansion, you will be given the option to use your Blizzard balance as a payment method.
Ok tyvm all!
