What's the absolute cheapest method to finish the education requirements for CPA?

I've decided to start studying for a CPA but it's been a decade since I've been in school. I've ordered a copy of my transcript and I'm sure I finished the Upper Division Business courses and I'm probably missing at least two Upper Division Accounting courses/equivalent Semester Hours requirement.

That being said, I do NOT want to reenroll in my old school or a state school. I've checked their credit hour costs and it's pants-shittingly high.

What have some redditors done in similar situations?
