Diesel prices on the east coast this year have had a strong regional component to them as well, considerably more than can be explained by the difference in state taxes. Here in SE PA right now, it's difficult to find diesel for less than $6.00, and the price at many retailers is pushing $6.50. Yet I bought diesel in South Carolina last Sunday for $4.89 and in Florida a few days earlier for $5.09. Tax in PA is $0.75/gallon, South Carolina: $0.27, and FL $0.36. So $0.40-$0.50 if the price difference can be explained by taxes, and up until this year, prices were in line with taxes, but this year there's another $0.50-$0.60 regional difference that I can't account for.
