parts washer fluid questions

Depending on what size you got, you'll need about 10 gallons of fluid. I picked up "parts cleaner" in 5 gal buckets at NAPA. If I remember its about $100 per bucket. I tried just 5 gals in mine and the pump wouldn't pickup.

This is what I've seen in my local auto parts store as well. But $20 per gallon?? Dang!
