THE BRONX - As gas prices rise around the country, some residents say they are fuming that it costs them more to pay with their credit card than it does to pay in cash.

Gas station owners say they are not breaking the law when they advertise one price, but charge another when residents pay with a credit card.  Under New York State law, a gas station can charge customers up to 3 percent of the base price as a processing fee.

Gas station owners say the fee is to make up for a credit-card fee that they are charged when they process a customer?s credit card.  They say sometimes they even lose money when customers pay with a credit card.
