How do you know it actually shipped? Did you get an email saying so with a tracking number or did they (Amazon) simply charge your credit card finally? I did get see a charge go through on Sunday but no follow up or emails other than that.
My card charge went through on amazon on Saturday. I had not received an email though so I contacted them yesterday on their Facebook page and they sent me a message stating it had shipped and gave the tracking number to me. They are supped to send out an email to you once it ships with a tracking number, but from seeing others comment on the Facebook page, it looks like that has not been happening for several people. I would just try to contact them there.
