More cheap gas

Driving through Valparaiso, on my way home from the kids', I see cars in line at a gas station. The sign read, "$168.9"!! I really didn't want to wait so I kept going. The next station was EMPTY. I stopped to fill up and asked the kid at the cash register what was going on? He mentioned that the stations on either side of him were selling for a penny less a gallon. I told him, "Eh, what's a penny??" he said, "Yes! I guess you're right."
Turns out I didn't really need gas anyway. Four gallons topped it off. :0)
