We've already gone through the StartCom verification process, but had only generated a few specific cert's for subdomains.

However, we're right now in the process of launching a new online project. No idea what subdomains will be needed in very near future.

It costs us no extra to generate wildcard ones, which obviously is the right move to do as they'll be valid while StartCom's new ones are no longer trusted (when Mozilla stops accepting new certs).

There's literally no way we could afford to pay for new certs from an alternative registrar instead.
