About gas prices in Delaware
Delaware's small size and density along Interstate 95 mean strong retail competition keeps gas prices below most of the Mid-Atlantic. The state gas tax is roughly 23 cents per gallon, lower than Pennsylvania, Maryland, and New Jersey. Wawa and Royal Farms are the dominant value-pricing convenience chains, with new locations opening regularly along I-95 and the coastal Route 1 corridor. Costco in Christiana and BJ's Wholesale in Wilmington draw membership-card customers from neighboring states. Delaware Memorial Bridge traffic from New Jersey often fills up in Delaware specifically to capture the lower tax rate.
