A new state law allowing gas stations to offer cash discounts has helped consumers save an average of twelve to fifteen cents per gallon, according to one trade group.

Michael Fox, executive director of the Gasoline and Automotive Service Dealers of America, said between sixty and seventy locations throughout Connecticut are now using the two-tiered pricing system, which offers discounts to customers who pay with cash instead of using a credit card. He expects even more gas stations will try the new pricing strategy.

"The issue...has been getting the signs," Fox said. "We did get a tractor-trailer load of signs in about a week ago. Now it's just getting them out there."

Fox said the new law, signed in June, is also pushing down prices at stations not offering cash discounts.

"We had only one location on the Berlin Turnpike in the beginning that started the two tiered, or cash discount, system. And the average price there went down ten cents a gallon to compete with that cash price in the stations that were not doing the discount for cash," he said.
