Discrete Math distance learning course?

Anybody know a school that offers an undergraduate course in discrete math via DL? I took it as part of my B.S. in computer science, but I want to take it again because I didn't really learn much the first time around. The only school I've been able to find so far is the University of North Carolina Online, but tuition is going to be more than $1000 not including books and thats just a tad too pricey for me for being a refresher course.

 

Athabasca University

I took it (online) from Franklin University.

If you don't need the credits, you could review using the Schaum's Outline or through MIT's Open CourseWare.
