I just found this today (at least it wasn't the day after it ended...):http://www.whizfolders.com/buynow.aspx
Basically, both Whizfolders versions are being discounted - but only for a few more days, apparently. You have to click on the respective "BUY" boxes further down the page. This takes you to the site's Store where the discount is applied automatically.
To get some idea of recent developments, take a look at the developer's blog:http://www.whizfolders.com/blog/
