Sunoco in Bloomfield (4068 Penn Ave)

seems to be consistently cheapest

Never go inside, but just buy gasoline

They still havent changed the prices on their sign! Regular gas is $4.19 NOT $4.39

Its a bit iffy

Its a very busy gas station and convenience store at all hours of the day and night, but usually pretty efficient and well-stocked, considering, but lines can definitely be long and parking is minimal. They do sell beer and wine here. All purchases earn Giant Eagle Fuel Perks if youre a member, which is a very generous program that offers substantial discounts on either gas or groceries. Bad things - the air pumps are free but dont work well, and are often completely nonfunctional, and COVID mask compliance is very poor. Strangely, they stock exceedingly little ice cream, if any.
