There are 2 ways to go:
1) Fresh account with pre-purchased amount of Vbucks with full access depending on platform you play. 2) I can add bucks on your current account. It will work for any platforms mentioned in the description
I can give you brand-new full access account with desired amount of vbucks on it. Add yourself as a friend and gift. But keep in mind game have limits of 5 gifts per 24h you can send. And you will be able to gift after 48h adding as a friend
I can recharge your current account via linked xbox account (you need to link xbox account with epic games and provide xbox email and pass - it will work for PC/XBOX/PSN) To simplify XBOX account linking just follow this guide:
