We have family sharing and we have a credit card on my husbands account and he's in charge of the family sharing. I would like to be able to choose my own payment solution sometimes and not have to go through the one registered on him all the time.
Anna,
Buy iTunes gift cards, and redeem them to your account. As long as your own account has a credit balance, any purchases made by you will be charged to your own credit balance, and will not hit the Family Organizer's credit card.
Here is the document for your reference:
Family purchases and payments
"After you set up your family, any time a family member initiates a new purchase it will be billed directly to your account unless that family member has gift or store credit. First, their store credit will be used to pay the partial or total bill. The remainder will bill to the family organizer's card."
