Gas stations in California certainly have different prices for CC vs cash, but they have to show both prices I believe. If you just charge extra for credit cards, that's a surcharge and falls under different rules. I think you can also advertise the credit card price and offer a cash discount. Debit cards still have transaction fees, though lower ones I believe, so they usually get the same price as credit cards, but none of the benefits like points.
