The profit - roughly .5 cents a gallon - is far less than what they are paying in taxes and credit card transaction fees.
Local gas station owners say they have to pay credit card companies 3- to 4- percent every time you swipe your card. That translate to nearly $200,000 a year. Their main profit comes from attached automotive shops and inside store sales, both of which are down.
The North Carolina Petroleum and Convenience Markets say they are fighting to lower the fees - a savings they say could be passed onto the customer. Gary Harris with the NCPC explains, "Right now a bill in Congress gives retailers the ability to negotiate with credit card companies set a fee so as prices rise the fee is set doesn't."
But for customers like Charles Boison, speed and reward points are motivations for using credit instead of cash. "If you're going to get a discount of 3 percent just pay here and you're out." Even if it means hurting business.
