Now, why should you compare the gas prices? Of course to find a lowest gas price so it won't affect your pocket as much.

If you have a vehicle that runs on gasoline, then you have undoubtedly noticed the outrageously high gas prices every time you are at the pump, as have most Americans and consumers around the world, which has led you to compare gas prices. Because most of us are trying to save a few pennies where ever we can, we find ourselves comparing gas prices at local gas stations in our area. It’s pretty sad when you have an economy car and it costs over $45 to fill up the gas tank. You hardly drive, and it still doesn’t last you more than two weeks at best. Now think of this scenario using an SUV as an example, and you’re looking at $65-80 to fill the tank on a weekly to bi-weekly basis. Long gone are the days when gasoline was less than $2 a gallon and you didn’t necessarily have to compare gas prices, and it really wasn’t that long ago, just a few years, less than a decade, 1999 to be exact. I’m sure most of you can relate to what I’m trying to say here.
