Normally use to go to this Costco location which is 3.5 miles from my home to fill up gas in my 2 cars...Gas rates elsewhere in towns like Edison, Iselin, Metuchen are Regular - $ 3.40 cash and $ 3.50 for credit, this location has it for $ 3.10/gallon with credit cards...No cash accepted on the premise at this location which is also a good thing (in turn prevents robbery and threat to employees)..Excellent service, long hose to fill the fuel on either side of the car...Always smiling staff who pump the gas in for you...Major benefit is you can pile up miles on your costco american express credit card or any american express card for credit card benefits...Always 5 ***** for Costco in terms of gasoline.
