Starting July 5, a Costco membership card will be required to buy gasoline at the stations run by the retailer.
Gas at Costco stations is typically less expensive than elsewhere.
The price for a gallon of regular gas at Coscto in New Jersey Tuesday was $4.83, about 20 cents less than the state average for unleaded.
New Jersey, however, has previously said restricting gas sales violates state law, and Costco and other warehouse clubs scrapped a similar plan in 2004 as a result.
The state Division of Consumer Affairs, an agency overseen by the Office of the Attorney General, has not yet commented.
