The company is also offering a $21 discount on all iPod classics and second-generation iPod touches. Both 40GB and 160GB Apple TV models are discounted by $21, and discounts are also available on the Nike + iPod Sport Kit, Airport Express, iPhone 3G Dock, iPhone Bluetooth Headset, and many other third-party products. The sale will run through midnight tonight.
