I've been looking at various CDN services, and many of them seem to charge a pretty hefty fee compared to the free shared SSL offering. One in particular, CDN77, is offering private SSL for $700/year.
Why is the price so high? Isn't the only technical difference between a private/public SSL the ability to use a custom domain name? From what I gather, the only difference would be having to send the key/certificate to them yourself, which shouldn't cost nearly $700 a year.
Do they just charge this price because they can?
