We do not charge for return shipping on old cores

We only charge if you do not return the core

Non Credit Card Orders:

All orders paid by any method other than a credit card (PayPal, COD, etc.) will require a credit card on file for the core value.

Core Return Procedure:

  1. Drain all fluids (oil, fuel, etc.) before the core is returned.

  5. Complete the included core return form and place inside the package.
  6. Apply the return service label over the original shipping label on the external package. The item must be shipped using the return service label for free return freight.
