What discount does the TESU Study.com partnership bring?

[Pelican]

I am confused about the TESU Study.com relationship. I thought it resulted in some kind of waiver of fees, but when I got to this page, it shows now a waiver of fees, but pay a fee called a waiver. I'm trying to judge whether this fee reduction is sufficient to warrant rushing to get my degree done quickly, or taking additional courses to get a dual major, which would make my degree much more valuable (I'm a secondary teacher, so that would show I have expertise in two subject areas instead of one). What is the nature of this discount?
