Schools with reduced cost for 1-2 classes?

[Ideas]

I'm just worried about dealing with too many transcripts, also there's probably the cost of the books...

Yeah, someday I would grumble about the extra transcript or two, but I don't think I will send transcripts that often. I don't think I'll be applying to more than 1 grad school in a year, and not many times.

I look up the books before I pick the classes, but I find that a lot are under $50 if you get a used copy or rent.
