Is the achievement still available from a MCT? I know it's not retired but I just wanted to be certain before I purchased one.

I just got it, so yes, it is :)

Oh cool :) How did it work? Did you just get the 500 CSC?

Yes, it came up with a screen that said I would get the 500 CSC. As soon as I clicked on the CSC to accept it, it gave me the achievement.

That'd work perfectly then. Thank you ^_^
