How Do I...Bypass initial payments.php page

[Simplicity]

Hi there,

I am linking to paid subscriptions for another location such as the header of the forum to be subscribed too or on a non vbulletin page. How would I go about bypassing the initial payments.php page which lists the various subscriptions available and forward the user directly to the payments.php?do=order area associated with a specific subscriptions.

E.g. Forum X,Y and Z have headers with subscription info and urls to their individual payment pages.

This way I reduce the number of interactions the user has to make to subscribe to a certain forum and also helps reduce any confusion, eliminating a vast list of available paid subscriptions.

Many thanks for any help with this
