Another good deal: Apple Airport Express for a little under Apple’s list price of $99. Use this to extend your wireless network, and/or to play your iTunes music from your Mac through your home stereo– wirelessly.
UPDATE: there’s a new version of the Apple Airport Express. Works like the original, but better.
And another: iWork ’09 Family Pack. This is the 5-installation Family Pack, at about the same price as the single-user version at Apple.
Amazon’s prices change so I’m not putting the prices in here. However, their prices are generally the lowest around. Always check them out.
