Guess what - this isn't quite what you said before. Let's see...
You still haven't said anything to prove a rotating price cycle. Whats said in your latest post could be attributed to transportation and distribution costs. Lets say that in Ohio, Columbus, Cleveland and Cinnci all have their own distribution centers, since they are the three big metro areas. It costs little to run tankers to local gas stations. The problem is that you still have all of the rural parts of the state that need fuel. So now, you've got a Cleveland tanker running down the interstate Cambridge, or a Cinnci tanker running to Dayton, or a Columbus tanker heading to Chillicothe. It costs more to supply these areas, so of course the gas station in that area will have to eat the cost of transportation. What is unfair about that?
