This really sucks!

First thing I'd do is call the post office and report the theft. I'm sure there's some sort of procedure that they have for such things. Then I'd call Amazon and report it as well. I've never had this happen to me so I don't know what their policy is, but it's worth telling them.

Is there an angle from a window that you could set up a webcam towards your mailbox? If so, you could do this and even put a small sign on your mailbox saying "you are being filmed" or something. Hell, just stick an unplugged webcam in the window and put up the sign and you're golden.
