Dang, what doesn’t printer ink cost more than? If you answered “Thailand cobra venom,” you are correct!
Printer ink is even more expenisve than party drug, and sometimes toy ingredient, GHB. These and other fun facts can be had on Cockeyed’s list of 47 liquids and their prices-per-gallon. It’s interesting that for all the kvetching about gas, it’s actually one of the cheapest per gallon liquids out there. Then again, we aren’t trying to run our cars on Cover Girl nail polish, although that could result in some pretty stylish exhaust fumes.
