I run a dedicated box, and have installed a secure cert on one of my domain names (which was purchased solely for this purpose, it's similar to websecurity.com, you get the idea).

I also run an online retail site, which obviously uses the secure domain for it's ordering section. (Let's call the site www.store.com)

Now the question. Do you think it's important that store.com uses https://www.store.com for it's secure section, or are visitors indifferent and is https://www.websecurity.com/store.com/ just fine?

We're talking about what, $100 a year, not going to break me What are your opinions? Stick with the generic security, or go for another cert?
