Gas prices are still rising due to the Iran war but drivers are saving by fueling up at tribally owned gas stations. Especially in California, New Mexico, New York, Oklahoma and Washington state, tribes exempt from state fuel taxes offer much lower prices than gas stations nearby. Apps such as Gas Buddy make finding such stations easy. Nationwide, average prices are up more than $1 a gallon since the war began but some tribally owned gas stations offer savings of 50 cents or more. As with other convenience stores, the real profits aren't in gasoline but selling snacks and, on many reservations, getting drivers to gamble in casinos.
