did it not come with the barrels? I figured you'd just need a warehouse and a truck.

(which is a pretty big ask, of course, and maybe free labor to pick it up up and move it into the truck...(

Barrels are over $50 each even in bulk. The oil is often less than the barrel, "1 barrel" of oil is a unit of volume equal to 42 US gallons. The price/barrel is the price of bulk oil, not oil literally transported in barrels.

Lol, no. When you buy "barrels" of oil on a commodity market, the barrel is a unit of volume (42 US gallons).
