How much are you really saving to be there for that sale? This is a true situation at our house. My wife drives a Dodge Ram, it gets 12 mpg (miles per gallon). Gas in our area is $2.45 per gallon. The mall is 18 miles each away. If she cuts back and only goes to the mall once a week, instead of twice a week, how much would she save in one year? ($7.53, $7.35, $8.35, or $382.20)
