I was on that page as soon as I saw Surt mention it in the chatterbox bit on the 23rd but never saw anything about 75% off else I would have bought it instantly.  I can't justify paying more as I have the 6.5 version and does most of what I need anyways.

Maybe it was just a one day deal?
When I wrote the news item and checked the link the 75% offer was on the top of the site.
 

seconding ChristopherG's comment -- I don't see anywhere to enter a promo code.

I don't see where I can input the discount code, it sends me straight to paypal

This is an excellent news that it is finally released.

I have followed the development of the new PM version since the beginning of the year as a beta tester and I can say that I am very happy with all the features/tweaks that have been implemented since the previous version (v6.5).
