Some info about the discount:

NoviiMedia announced the "NoviiRemote Blaster sale" and the Treo 650 users got a last chance of acquiring this accessory. As far as the goes, there are only 500 blasters left in stock and no blasters will be available after these are out! The Noviiremote blaster is the only way to use Treo 650 as a remote control for TVs, DVDs etc. from a good distance.

The Noviiremote Blaster is available 50% off ($17.99) and the offer lasts as long as the blasters are in stock.
