MegaMacs has the Apple Wireless Bluetooth Keyboard, model no. MC184LL/A, for $39.99 (69.99 – 30 instant savings) for a limited time. Shipping adds $10.48. Deal expires February 8, 2012.

The sleek and completely cable-free aluminum Apple Wireless Keyboard uses Bluetooth technology to provide up-to 30 feet of connectivity with your Mac or iPad. Its compact design takes up 24 percent less space on your desktop than full-size keyboards, so you have extra room to move the keyboard around and mouse comfortably alongside of it. You’ll also feel a difference when you type on its low-profile anodized aluminum enclosure with crisp, responsive keys. Use the function keys for one-touch access to a variety of Mac features such as screen brightness, volume, eject, play/pause, Exposé, and Dashboard.

The Apple Wireless Keyboard requires just two AA batteries, and its intelligent power management system conserves battery life. So when you’re not using the keyboard, it automatically powers down. The instant you start typing, it turns back on. Use the on/off switch when you’re away from your computer for a long time.
