Aha! I just discovered why Shell could offer $2.00 gas coupons!
I took the following shots on Father’s Day, June 18. Notice that the Shell price per gallon, in Rutledge, Tennessee, is 7.5% higher than
the Appco price, in Rogersville, Tennessee!
I assume that the extra 0.5% went to administrative overhead!
Seriously, how was a 21-cent per gallon difference possible, or justified? This confounds my one brain cell!
