MacUpdate today announced the launch of a new program called the MacUpdate Promo. Every weekday, the site will feature a new software title on the front page sidebar, giving Macintosh users the opportunity to purchase that title at a steep discount. For example, today users can purchase iClip at a 40% discount. This is a great deal because you will receive a free upgrade to the highly anticipated version 4.0 release, which will cost considerably more than $12. Each promo will run for only 24-hours, starting at midnight (ET).
