Tick "Add?" for each kind you want and enter a quantity. There is a minimum for each kind.
Choose "Checkout" and pay. An invoice is created.
On the "Billing" page, choose "Convert credit to another kind".
Choose what to convert from and to, and how much.
Check today’s rate, tick that you understand conversion is final, and choose "Convert credit".
