$3.16 in middle TN.
$3.22 in Pearland, TX - Houston suburb to the south. Significantly more in the city.
$3.09 here in SW South Dakota; 5 cent discount if cash or check instead of plastic; another bonus 5 cent cash discount on Wednesdays. Two weeks ago, paid $2.89 in Rapid City.
Not worth driving 60 miles each way just for it, but when we do go, I dry-tank up, then fill up & also fill the cans for the tractor, garden tractor, and tiller.
Price has been pretty stable for the last 3 weeks.
