There is no cost. You only paid the initial enrollment fee of 895 and subsequent years, the annual student fee of 495. That's it. Even after you get your initial transcripts in, you can obtain more certs. Example, I can sign up and get my transcripts sent over, then say 6 months later I get my MCSE, I can get those added as well for no additional costs. I know some school do charge for some PLA for each additional units. Excelsior doesn't charge like that.
