Why do (most?) American gas stations use physical, numerical signage that require manual adjustment when prices change? Wouldn't electronic signage make life easier and maybe more profitable? Is there some regulation that requires non-electronic signage?

Gas (petrol) question: We've had discussions in the blue about regional price differences for gasoline. But why do different gas stations in the same market region come so close to each other on price? Are the markets for the raw oil and the refining so limited that they all end up with the same cost? I find that hard to believe. Also, is there any difference, in real terms, between gasoline from one vendor versus gas from another?
