How to find the best gas prices
Take a mental note daily of the gas prices as you drive throughout your local area.
Stop and fill up at the place with the lowest gas price you saw. When traveling long distances, pay attention to the gas prices in various areas so you can have an idea of where to fill up on the way back home.
Call and talk to your friends who drive past other fuel stations in the area. Ask them if they notice a price lower than what you know to be the best price, and visit that location.
