I took a short trip today and discovered something very interesting. The two highest priced diesel fuel prices were at the Flyhing J and Loves ($3.43 credit card, 3.38 cash). Around Spring where we are staying, prices are $3.25. I paid $3.15 at Wal Mart but could have bought it near home-base at Kroger for $3.07 with the .10 per gallon discount.
