matsam, what happens when you try and track it with the email confirmation from Dell? It should let you know. I've never had to wait more than 2 days for anything I've ordered from Dell. Maybe you can give them a call, they are usually quite friendly.
In fact I bought my ps3 from dell during one of their dells, and I called to return the ps3, because I had buyers remorse, and the lady on the phone offered to return 50$ to my credit card. So I say call them up and see what they say.
Good luck!
