Here in West Palm on Military Trail all gas stations are at war......good for us. My neighbors dad's friend started it all.
He owns a Chevron and purposely puts his gas price roughly 5 cents cheaper then everyone else and it's forcing the other stations to come close. Cheap stuff $3.64 so premium is about $3.87.
However, I was in Chicago last month and the cheap stuff was still $4.25!!!!!
That is the cheapest I found. I saw the expensive stuff up to $4.85.....ridiculous!
