Cheap, yes cheap wildcard SSL?

Sorry for posting so long after the initial discussion, but had something to chip in

Wildcard certificates make sense in cases where you have many servers or subdomains. If you just need a simple certificate for an additional subdomain, getting a plain certificate should work without issues, and would cost much less.
By the way, with the main domain you usually get the www too, so you do not need to pay for it.
