“Out of gas” signs were reportedly being posted at stations in the Dallas area as consumers rushed to stations to top off their tanks in anticipation of gas shortages. As a result of the demand, Dallas-area operators raised prices dramatically, in one instance from $2.99 per gallon pre-Harvey to $2.99. C-store chain QuikTrip temporarily halted gas sales at about half its 135 Dallas-Fort Worth-area stores in order to regulate distribution flow.
