Not sure how long this has been going on. I know quite a few readers here use GasBuddy to check fuel prices, but I'm not sure what other fuel retailers specifically advertise their individual locations' fuel prices. It does require clicking on where it says "Gas Station". I picked this one because it's alphabetically the first one that has diesel.
