Do you tend to buy your gas at the same place most of the time? Do you just get in the habit of always going there or do you look around and compare the prices on a regular basis? I admit it. I've gotten a bit complacent since gas prices are so much lower. The station where we usually buy our gas is the cheapest most of the time, so I tend to just go there. This past week, I noticed the price had jumped up, and not just a couple cents. I was thinking that a gas station I passed a couple minutes earlier was cheaper. Since we still had errands to run, we decided to wait to buy gas and have a look around. Just a few blocks away the gas was nearly 20 cents cheaper per gallon.
