You can apply to get a free Microsoft Office 2007 Tips and Tricks CD from the Microsoft Small Business Centre web-site. Even though I am in Australia they let my application go through, which is a rare thing, so I suspect that it should be available from anywhere in the world.
You will need to sign up for a Microsoft Passport ID to log in for your free Microsoft training CD, but if you already have an ID you can just sign up with that.
Here is the link:

After you have signed up you will also gain access to other training resources, in addition to the free training CD.
