I paid $1.67 for regular on Monday. However, in Mass. 75 cents of your gas is strictly taxes. Those of you with the lowest prices ($1.25, etc.) don't have as much tax as we do.
A station owner told me one time that if the station gets the gas from the gas company on credit, the then gas company gets to set the price. If the owner pays cash, then he gets a discount and can set the price wherever he wants.
