We do not ship large or heavy items to PO Boxes.
We generally ship with USPS however on larger or heavy packages we utilize FedEx, UPS, and YRC.
We do our best to get packages out the same day on purhcases made before 2:00 PM PDT.
With the high cost of shipping we are always searching for better more economical ways to ship. If you find a better rate let us know so we can help to save you money.
