When you purchase a product from our website that has a core requirement, you have two options:
1. You choose to pay the core charge and we will ship the product right away, then once we receive the cores you will be refunded the core charge if your cores pass our inspection qualifications. This is the preferred choice and has the least delays.
2. You choose to send in your cores before we ship the product that was purchased. This choice has the risk of delayed shipment of your purchased product and our inventory is not guaranteed by the time we receive your cores. You will need to follow all of the instructions below as quickly as possible so that you can get your purchased product and we can receive the cores. When you choose this option you acknowledge that by the time we receive your cores, our inventory could have change and there could be a delay in your shipment.
Please return all cores to:
