If you select Free Shipping or 1-3 Day Rush Shipping as your shipping method (available for online orders shipping within the USA), we will use the most economical USPS (mail) or UPS Ground method that meets the arrival time estimate.
For this, if your physical address is serviceable by both USPS (mail) and UPS, then you only need to enter your physical address.
If your physical address is not serviceable by USPS/Mail (or if you cannot receive mail at your physical address), then please enter both your physical address and PO Box or mailing address. In this case, you may use the shipping address line 2 field to include your PO Box if city/state/zip are the same as your physical. Or if you need more space, please use the special instructions/comments box directly below the city/state/zip fields to include the alternate address.
Paid Shipping Instructions:
If you select a paid method of shipping (not free shipping), then you will need to enter an address serviceable by the paid method. For example, if you select UPS Ground, UPS 3 Day Select, or UPS 2nd Day Air as your paid method, then you must enter a physical address (not a PO Box). However, if we are shipping your order to an address outside of the USA, your order will most likely ship via Priority Mail International. For Priority Mail International, both physical addresses and PO Boxes are allowed.
More Info: What if I only enter a physical address and choose Free Shipping?
We will attempt to ship your order to your physical address using either USPS (mail) or UPS. If we find that your physical address is not serviceable by the most economical method (depends on order weight and destination), we will contact you to request an alternate address.
What if I only enter a PO Box address and choose Free Shipping?
We will attempt to ship your order to your PO Box address via USPS. If we find that we can ship your order more economically via UPS (depends on order weight and destination), we will contact you to request a physical address.
