Ever wonder why some gas stations charge more than others in the same city?

The above is at the 805 and Adams...

The above is in Pacific Beach, and is 14 cents more... well, I guess in that sectioned off area of San Diego, there aren't a lot of gas stations, and they must realize few people will drive very far to get cheaper gas

So is anyone going to let these guys in on the news that they are 2 blocks away from gas that's 77 cents a gallon cheaper? And that just 15 minutes away from gas that's 91 cents a gallon cheaper?

By driving 2 blocks, 10 gallons is nearly 8 dollars of savings. Why would anyone waste their money at Chevron?
