We could even see a handful of stations in places like Oklahoma, Texas, or even Wisconsin drop below $2 per gallon in the weeks ahead — something not seen since the pandemic. In addition, with wages up and gas prices down, Americans are spending the smallest share of their paycheck on gasoline in many years.” Share via: Facebook Twitter LinkedIn More
