Michigan Attorney general advised all stations to NOT price gouge! We have some of the highest prices in the lower 48 most times.
Here is how our state works. On Monday afternoon prices go down (because people from the weekend filled up on Sunday). On Thursday morning, prices go up (they got smart because people filled up on Thursday for the weekend). Funny thing. During the week, gas might be 2.45, then go up to 2.65, then back down to 2.55. It is priced to make you think prices went down when the average remained far above the norm.
It was 2.69 on my way to work this morning. We have refineries in the Detroit area and across the bay in Wisconsin. And it still doesn't matter. Heck, I have a pipeline that runs through my property!
