DOMESTIC SHIPPING--continental United States We ship within 1-2 days of receiving payment. We require a physical address for shipment. Our shipping agent is UPS Ground, and they will not deliver to a P.O. Box. If you absolutely have to use a P.O. Box, we can use USPS Priority Mail, but the shipping charges will be somewhat higher. Please email us if you need an alternate shipping agent to be used. INTERNATIONAL SHIPPING--any location outside the continental United States All international packages or those to Alaska, Hawaii and U.S. territories are shipped via USPS Priority Mail.
