The wholesale spot-price for regular in Los Angeles is 35 cents. That's what the oil refineries are selling it for, and losing their asses in the process. Big time. They bought crude at $40/bbl and are giving the finished products away at a fraction of the cost to refine it.

That does not include a bunch for fed, state and local taxes.
What is really going on is gas stations have tanks full of gas they paid a lot of money for and they don't like the idea of selling to for half of what they paid for it.
So they are keeping the price high knowing they will have to sit on it for a long time. They are hoping the price will climb a little so they won't lose so much on it. Survival of the small businessman.
It's a waiting game as the product has a limited shelf-life.
Eventually they'll have to dump it all at a very low price if demand doesn't pick back up, and they are trying to postpone that inevitability.
Make sure you buy your gas at a station that is busy and moving lots of gas, not just Doritos and beer.
Note that most gas stations are independently owned, maybe by one of your neighbors.
