Another way to find some of these materials is to post a request for them on your local Freecycle community. I've had lots of luck with this service; It's a great way to get secondhand items you don't want to pay for.
I preordered from them and still no word. My order status is still expected to ship yesterday, 12/4, with no tracking number. Glad to know people are receiving them, though! I was afraid they weren't even going to exist.
I'm playing with the beta patch of 1.03 and I'm having a blast. Even after the game's over, the upcoming user-created content should keep it fun for years to come.
If you couldn't pick this up at Best Buy for $25 on Black Friday this sounds like the next best thing.
