However, Gas War Alley has been being beaten on price lately from time to time by the dueling BP and Shell stations near where I work -- still in Cook County! Yesterday, the BP station was at $2.019, a penny or two less than the Shell station across the street, which has been the norm for pricing.
This morning, the Speedway on Touhy was at $1.989. The BP was at $1.999.
Until the Shell station lowered its price to $1.979 while I was on my way to lunch. By the time I'd finished lunch, the BP has lowered its price to $1.979.
Since I had about a gallon of gas left in my tank, I issued an immediate buy order. :)
Update: $1.989 tonight at the Citgo, $1.979 at the Jewel.
