I need to add part(s) to my order that has not shipped yet, how do I do this?

We understand that sometimes you might forget an item or two after placing an order. If this happens, please follow the steps below to request that your new order is shipped with a previous one:

1. Place a new order for the items you missed. We suggest doing this as soon as possible.
2. At checkout, in the comments box, please specify, "Ship with previous order (include your original order number)."
3. Once both orders are finalized, if there's any extra shipping expense due to combining, we will review and process a partial refund after shipment.

While we always strive to accommodate our customers, please note:

- No items can be added to orders once they are submitted.
- We will do our utmost to combine your orders. However, due to high processing volume, we cannot guarantee that your orders will be combined. If we're unable to do so, your orders will be shipped separately.

Thank you for understanding and shopping with us!
