I'd guess yours is still sitting in customs, but that's really just a guess. Shipping times from China to anywhere else seem to be all over the place. Same applies even to shipping stuff from the US to Germany. I've placed several orders with threadless.com and while the last one took merely 8 days, I've had others take at least 4 weeks. So with cheap international shipping: be prepared to wait
