The USPS tracking number Strymon provided me is incorrect.

For products shipped internationally USPS recycles initial tracking numbers. Unfortunately, this is beyond our control however, once your order reaches a USPS main distribution hub (usually within 1-3 days) USPS will re-scan your order and update the tracking information without changing the tracking number. We recommend waiting a day or two before you check your tracking. If after that time, your tracking information has not changed please contact us and we’ll look into it.
