Purchase Paid Subscriptions with vbux?

How can you purchase paid subscriptions using vbux?

When visiting /payments.php I see the cost of the subscription in points along with my setup subscriptions, however - there is no way of actually purchasing the subscription using the point system.

Am I overlooking something? Paid subscriptions are infact integrated, correct?

Thanks in advance.

They are integrated from the standpoint that you can give people Bux for purchasing a subsciption, bu they can not purchase subsciptions in the vBulletin system with Bux.
