Prices usually fluctuate at any gas station, which usually depends on the area or the cost of living in that Providence.
United oil tends to be one of the cheapest in the area. But here is a rant in response to the prior answer. There is no such thing as watered down gas. Having any water in gas would ruin it. All gasoline of the same grade (octane) is basically the same with many brands getting their gas from the same whole saler. The only difference between brands are the detergents added and there is very little or no correlation between detergent quality and price.
It varies but i find it one of the cheapest ill drive the distance to get gas there for a cheaper price and it burns slower in my opinion so not watered dwn...
