While I would never use them for domains, I did buy a $12 SSL cert back when everyone else was charging hundreds of dollars for the same thing. Before someone points me to a free SSL service, this was for an enterprise class application that was more about security theater than actual security. I was able to get away with GoDaddy instead of Verisign, etc. because my client used GoDaddy for their domains – go figure.
Careful, they'll autorenew those at a much higher price. Mine went up to $100+ when it renewed last month. I'm kicking myself for being stuck with that cert, especially since the GoDaddy badge isn't exactly the mark of trustworthiness.
