I try and buy the cheapest gas I can buy. Today I passed one station for $4.64. Then I bought my gas for $3.75. That is about the cheapest around town. I do not drive all over town to find a good low price. I happened to be passing . Many stations have no price listed and have yellow plastic bags over the handles. By the way, I live in Valdosta, GA.
The first car I owned was a '67 Rambler. It took 20 gals and I paid $5.00.
