You're right about that, Giok. The farther away you get from the Interstates (Motorways) here the higher the prices. Go to someplace like Dingle (Idaho, not Kerry) and you might be confronted with one station -- and if you want/need petrol (or anything else) you'll pay what they charge.

Now -- sometimes around here you'll find lower prices in the country! That's because the prices don't go up until a new shipment arrives. Not often, mind you, but I've seen it happen.
