 The Maker's Market is free for the public, but anyone can rent the space for events. I'm Rachel Suga, WDEL, Delaware's News Radio. If you're gassing up your car in Delaware, be prepared to pay around $3.46 for a gallon of regular gas. AAA Mid-Atlantic reports the cheapest gas prices are in Sussex County right now. Diesel fuel prices have gone up over the past week, I should say, to about $3.80 a gallon.
