Since we use multiple facilities we cannot guarantee any shipper couriers. We do not recommend using PO Boxes as we can't guarantee the order will be shipped using a courier that can deliver to the PO Box for example UPS and Fedex do not deliver to PO Boxes. 

If the order is shipped to a PO Box and the courier cannot deliver the order a return to sender (RTS) will be processed depending on what address is on the return label (our CS office OR your own address setup in the TL account settings) that is the address the order will be returned to.

If you are using our CS address the order will need to be delivered back to Sioux Falls, SD for us to reship and we will also have to recharge you the shipping fee as we are charged on our end to receive the returns and then to reship it.

If you are using your own address you would need to pay to receive the return back and cover the cost to reship.

We do not replace or refund on orders that show RTS we can only ship to an alternative address once received back to our office.
