Always has the cheapest gas prices. If you have their credit card you can get another .10 off.
This place is now Exxon and isn't accepting GasBuddy for payment. Remove it from your list.
At Sunoco, sometimes their definition of "premium" differs from most anyone else, especially if you need premium fuel. Their "bait n switch" is their advertising premium at a certain price, but in my experience it was 91 octane. Not bad, but 93 octane was $3.95/gallon, much higher than other stations with 93 octane fuel.
