Rising gas costs led to higher prices for items and services like food and shipping earlier this year. However, as the price at the pump settles back down, not all of the savings are being passed along to consumers.

Many businesses say they are still paying delivery surcharges despite the gas drop. That surcharge is often passed onto patrons.

"Surcharges are the same," says Mike Patterson, who owns the pizza and ice cream shop What's the Scoop. Patterson's experiences are echoed by the owner of Main Street Trattoria.

"As far as fuel charges being taken off invoices, it hasn't happened yet," says Tom Mezzetti. "I'm beginning to question why."

Federal Express and U.P.S. are bucking the trend, however, and have announced a 1.5 percent cut on ground transport fees. Both companies base their surcharges on the average price of oil and adjust it once per month.
