I went through the menu. The deal isn't exactly hidden, but it isn't announced on the home page, that I could see:

I also got Paint it! for $10CDN for buying other Corel product. Add it in on your cart page, where it says to continue shopping at the left-hand side near the bottom.

Full=$29.99CDN, Upgrade=$24.99CDN Full price is $99.00CDN, so this is a great deal, especially with the extra apps. I also got a book on how to use PSPPX3 that was offered at a good savings. I chose boxed. For Ontario, for example, shipping is a flat $13.00, just because I think commercial CDs are more likely to last longer than home-burned ones. They also offer 2-yr download protection, for a price. This means you can still download for 2 years after buying.

I don't know how long this will be available, there is nothing on the page that says.
