Yeah, it's by state and also by company. I think there is a base price and then every state levies a different level of tax on it. Then after the taxes are set, each individual company is free to set the price to whatever they want within a range around that base. It changes daily. So you might go to one station and it'll be $3.13 and then a mile down the road a station has it for $3.09. Then the next day those numbers might be slightly different. There are also a few bulk "warehouse" stores like Sam's Club and BJ's that have their own stations and if you are a member of that store (that you pay a yearly fee to use) you can use their gas station and the gas is usually 10 cents a gallon cheaper.
California and Hawaii generally have the most expensive fuel, California is at $4.70 right now. The southern, more classically tax-free states like Oklahoma, and Texas usually have the cheapest. Oklahoma right now is at $2.91.
