Please NO PO Boxes, we prefer street addresses only as we primarily ship UPS. The $7.95 flat rate shipping we offer, applies to the continental U.S. only and does not include Alaska, Hawaii, Puerto Rico, Virgin Islands, Guam and APO/FPO addresses. We can however, ship up to six jars at a time to these locals using the USPS Flat Rate Box for the $7.95 per order charge.
