I had to buy some for my rams front axle after I rebuilt it. It calls for 75w140 like 2.5 quarts so I had to buy three. I couldnt believe how expensive that crap was.
Not surprising given how often people need to buy it. The petroleum business makes profit on volume and lower volume means they charge higher prices for the commodity.
If McDonalds only sold 10 hamburgers per week at each location, imagine what they would need to charge for a burger to stay profitable. The oil business is no different.
