Costco's lower prices could boost its business as consumers face rising energy prices, according to analysts at Gordon Haskett. The firm found that in the first two weeks of March, traffic at Costco gas stations increased due to the U.S.-Iran war and rising oil prices, and that Costco's low prices could help. The company's historical pricing studies indicate that Costco gas prices typically run at a $0.09 discount compared to other local competitors and a significant discount on the state average.
