Core Charge…..



A “Core Charge” is similar to the deposit you might pay for a can or bottle of soda. In many states, to promote recycling, you are charged a deposit when you purchase a can of soda and you receive your deposit back when you return the empty can. Many automotive parts have a Core Charge, or Core Price, that works the same way as a soda can deposit.

Here’s how the Core Charge works:

  • The part you are purchasing contains a component that is recyclable
  • The Core Charge deposit is charged at the time of purchase
  • When the core is returned to us, the charge is refunded to you

To receive your Core Charge refund, you can do either of the following:

  • Bring the part to any of our Southeast Power Systems locations store along with your receipt or packing slip within 60 days of your purchase.
  • Mail the part back to any of our Southeast Power Systems locations following the directions explained here below within 60 days of your purchase.

Core Returns:

If returning a core item, please also follow these additional guidelines:

  • Remove any items from the core that may be needed for the proper installation of a new replacement part.
  • Empty fluids from the core. Enclose the core in the box and seal.
