We all can hardly wait to get the Humaworm, but you need to allow a minimum of 2-3 weeks to get to an overseas destination. If it was mailed on the 30th, I would wait until the end of next week before getting concerned. You will be pleased once it arrives.
Is it possible that customs may have interceded - we have had that problem in Australia and customs seized the Humaworm and didnt let us know for another 10 days after.
