The link below takes you directly to the Microsoft Windows 7 Pre-Order page where you can save about 50% off the release price. I am not going to debate the whole Mac vs PC deal because I really believe in whatever makes you happy, that way everyone is. So if you are a Windows user this is a great deal, I have been experimenting with the release candidate (RC) version and it has been a positive experience. You can get it shipped to you or as a digital download on the day of release.
