Single day parking for finals help

I'm a commuter and I didn't purchase a full week for finals since I only have finals on two days. I have only one on one day but two on the other that spans from 8 am - 6 pm. Are there cheaper options like a commuter specific daily pass? I saw there was $2 per hr at ARC but is that worth the walk when my final is at 8 (and also do they check if you go to campus instead of the ARC?).

Does anyone have any advice to get cheaper parking for literally only 2 days? Or happen to either have a parking pass they won't be needing Tues/Thurs they'd be willing to sell for cheaper
