Harman Kardon SoundSticks II 2.1 Speaker System: $114.84

The list price for these is $169.99, so they are discounted by 32% for a savings of $55.15.  You're saving even more money because you don't pay taxes in most states, and shipping is free. I've got these on my Amazon Wishlist.  I saw them at the Apple Store this past weekend and these things are awesome.  Not only do they sound great, they are clear plastic and have an ominous blue glow to them.
