Outside of the high pollution cities pure gas can be found.
Still more expensive but not hardware store pricing

Interesting! I just searched for pure gasoline stations and found this link:

Of course, where I am in Massachusetts there are no pure gasoline stations listed though there are garden centers and racing shops. I haven’t been to a racing shop but garden centers are even more expensive than the megalomart hardware stores.
