We will accept returned parts in their original packaging within 60 days of the invoice date. Call Customer Service at (732) 240-3696 to obtain a Returned Goods Authorization (RGA) number, which must be prominently displayed on the outside of the box when returned to Hamburger’s Superchargers. Returns must be shipped prepaid. Returns that are 30 days or less from invoice date are subject to a 15% restocking fee; returns that are 31 to 60 days from invoice date will be subject to a 20% restocking fee and will only be issued credit, good for future purchases at Hamburger’s Superchargers. Our Receiving Department is not authorized to accept COD shipments or returns without an RGA number.
