I remember a while back someone asking the board sponsor if they will ship other carriers and his response was no, USPS only since they can not open package. This lead me to believe ups and fedex can open your package at their discretion but I could be wrong.Originally Posted by MuscleInk
Either way, as long as it's packaged good as to not break and leak, I wouldn't worry much regardless of the courier.
*edit - from fedex terms & conditions: Inspection of Shipments - We may, at our sole discretion, open and inspect any shipment without notice. Governmental authorities may also open and inspect any shipment at any time.
