Not so much a way to save money with coupons but still a great savings idea. We live in a smaller community so the supply and demand of gas dictates the prices at our local gas stations. We had a trip out of town to visit a doctor that practices in larger community. Now we are fully aware of the gas prices being less so we chose to take the wife’s car because it was lower on fuel. We purchased 16 gallons of fuel which was $.10 a gallon cheaper saving us $1.60.
Now I wouldn’t recommend traveling 40 miles out of your way to save money on fuel. You have to use your own judgment of whether the cost saving justifies the trip.
