Drove into a local truck stop which always has the cheapest premium in the county of sale, and noted that the price on the big board was $3.83. Muttered “damn” under my breath (local gas prices have jumped 40 cents in 6 weeks), went to the pump, noticed it had premium at $3.77. As I finished putting my 11 gallons in, I noticed that the price on the pump had jumped 6 cents to match the sign. Score!
