A Great Bend Tribune reader complained over the phone this week about the continued resistance by local gasoline retailers to lower their prices. Pump prices in Great Bend have been locked at $3.43 for weeks, even as they have tumbled elsewhere, making the per gallon cost among the highest in Kansas.“That is robbery,” the caller said. “Great Bend is getting to the point you can’t afford to live here.”That may be an exaggeration, but the sentiment is understood.
