A "core" is what the industry calls your old defective part. We want cores to rebuild, recycle and/or resell.
Many of our parts have refundable core deposits. This means you pay a temporary deposit at the time you buy a part. Then, we fully refund the deposit once you send us your old part. Unlike most companies, we provide you with a FREE RETURN SHIPPING label to send back your core. (This label is good for use only in the contiguous 48 states.)
Here's how it works:
- You purchase the part you need to fix your vehicle.
- You pay a temporary refundable core deposit. Don’t worry, you’ll get this back!.
- You ship us your old part (the core) for free.
- When we receive your old part (the core), we refund you the full amount.
If you have any questions about core deposits, please feel free to give us a call at (888)-907-7225 and we will be happy to assist you.
