The mobile just got one of those electronic signs that can be changed ever so easily, while the shell across the street still has to use a pole and ladder to change their prices. I think mobile just gets a kick out of messing with them most of the time.
No, mine's always been more than that actually. I filled up when the gas light first came on, which showed I still had about 15 miles to go. Normally it's pretty close to 25 when I'm running on fumes.
I paid $2.50/gal for premium last night. Seems to be on a steady decline too. This was at a Chevron which is usually more expensive than the places in town, but they are too far out of the way.
