$199/year for 30 student licenst with one teach license

this is on the IXL website.  Keep in mind, I did not do this to make profit.  many group share the 30 student license if they can find 30 students.

I don't know enough people to share with me, that is why I ask from internet.  I even think $79 is not expensive, but the people who share the membership with me think even $30 is too expensive.  so I have to find more people to share so that everyone's cost is lowered.
