We ship all in-stock items within two working days of receiving your order and usually within 24 hours. All orders deliverable to a Post Office Box address will be shipped by Priority Mail from the U.S. Postal Service. U.P.S. does not ship to Post Office Boxes. Orders are generally shipped via ground service unless the customer specifies faster service such as two-day or three-day delivery. International orders are shipped by Priority Mail International unless otherwise specified by customer. Occasionally an item may be back-ordered which will cause a delay. In such cases, you will be notified by email or phone. Feel free to contact us with any shipping questions at: servicedirect@b-naturals.com.
