Why can gasoline stations charge 10cents more for gas then if you pay cash?

Gasoline stations often charge more for credit card purchases due to the transaction fees associated with credit card processing. These fees can range from 1% to 3% of the sale price, which can significantly impact the station's profit margins. By offering a discount for cash payments, stations incentivize customers to pay in cash, allowing them to avoid these fees and maintain better profitability. This pricing strategy also helps to offset the costs of accepting credit cards.
