We currently only ship our products within the USA. Some products can't be shipped by USPS Priority, so on a few items there is an extra charge for shipping to Alaska, Hawaii, U.S. territories. Our customer service team will contact you before the product is shipped to approve any extra charges to those areas.

In the same way, orders placed on holidays such as New Year’s Day, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas Day will be shipped on our next full business day.

Please note that a few orders may be shipped in multiple packages, so delivery times may differ slightly. You will receive a detailed order confirmation email with each online order, and notified of any delays. We do not offer C.O.D. orders.
