I’ve long been aware of one chain of gas stations that openly charges cash customers less per gallon than credit card customers.
Apparently it’s not alone. According to a local paper, the Contra Costa Times:
You’re getting charged for using a credit card - up to 3 percent per gallon - and may not have known it. …
Typically, those who pay with credit or debit cards are charged a fee that’s included in the advertised gas prices, and those who pay cash aren’t charged that fee - between 1.5 percent and 3 percent per gallon.
Who knew?
Yet another reason to use a gas rewards card that pays 3% to 5% for gas purchases. Otherwise you’re subsidizing everybody else that does, not to mention paying too much for gas.
