Oil and Water

Am I getting this wrong?

Oil is trading around $26 per barrel right now.
Doesn't that make it cheaper than a gallon of drinking water from the store?

Yes, your price comparison is wrong. Retail packaged potable water verses unrefined crude oil sold on the wholesale market.

1. That $26 per barrel of oil is a measurement of crude oil.
It is not actually packaged in 42 Gal drums (barrels).

2. Crude oil is not sold on the retail market like the gallon of
water you are comparing the price to. There is absolutely no
retail consumer demand for crude oil.
