Gasoline prices are on the rise in parts of North Carolina and some station owners say the price is up because of delivery charges. Triple-A-Carolinas says the average price for unleaded in the Triangle is two-dollars-90 cents a gallon. But prices at some stations already are up to three-dollars-nine-cents a gallon. The owner of a station in Durham says the cost is being boosted by delivery fees as well as credit cards, which charge stations a fee. He says he makes a dime a gallon when people pay with cash but just over two cents when they pay with credit. Stations in the Charlotte area also are boosting prices past
three dollars a gallon. Some owners there say they are having trouble getting regular deliveries. About half of 32 station surveyed in the Charlotte area say their prices are between three-ten and three-20 a gallon. The rest are about two-90. The director of the state petroleum marketing group says drivers can help by not topping their tanks.
