Do you save by going to a gas station with a cheaper price? It depends how far away it is. A new website helps you calculate exactly how you should drive in order for it to be worth to save on gas.

According to the site:

For the example of a 15-gallon purchase for a car that gets 25 miles per gallon, the motorist should drive no further than 3 miles away to pay a nickel less than a $3.15 local price.

You might think that you are saving when you drive a bit further to a gas station with a price listed 5 cents cheaper, but is it really the case? Consider that you have to drive to the gas station and back, adding extra miles on your car.  The creator of the site said “The total cost of a purchase should always be considered, not just the price. In many cases additional hidden expenses can wipe out any savings on price.”
