They didn't all ship on the same day, some people were saying theirs shipped on the 26th. In the US, it shouldn't take over 3-4 days (the USPS site claims 2-3 for Priority). Overseas though, don't worry yet. Overseas orders are also shipped USPS International, and they're not as fast as in the US 
If you send an email to sales@stardock.com, they will be able to confirm if it shipped and probably when. Note though that USPS doesn't do shipment tracking.
