^don't think so. I can see Shell gas station in downtown near my work everyday, and everyday their price is 30 cents more then the rest of city. I always wondered which idiot would fill up there? I did fill up there once, when my car was empty and I had no choice, bu filled only couple gallons to fill on the way back on different station.
If I would own my own Shell for example, I would drop price immediately in that situation,like 15-20 cents less than rest and have a huge line of cars to fill up. I've seen it once for about 2 years ago when we got hit $4 gas first, at some old [censored] station,and their price was only 10-15 down.
