Well, don't wait to hear it from me. I was thinking today that my order should have arrived by now, so I hit Amazon.com to check the status.
I was like when I read:
Items not yet shipped:
Delivery estimate: December 18, 2007 - December 20, 2007
* 1 of: Accutire MS-4021B Standard Digital Tire Gauge
* 1 of: Internal Combustion: How Corporations and Governments Addicted the World to Oil and Detrailed the Alternatives
* 1 of: Small Business Taxes Made Easy: How to Increase Your Deductions, Reduce What You Owe, and Boost Your Profits
I think the second item is the culprit -- it was mentioned here somewhere and sounded interesting, so I decided to snag a copy. I ordered paperback but I think it's only available in hardcopy right now.
Now I have to decide if I want to give myself a Christmas present in a half year, or bump the shipping up from free "Super Saver" so they'll go ahead and ship what they can now.
