Since it's so hard to find right now, I thought I'd post the right web page for updates. It seems many people got directed to the wrong page. And sometime today (I think) a direct link via a button on the Logos home page disappeared, leaving only a button that gives you full price.
Here's the correct web page to see what discounts Logos believes you are entitled to:
http://www.logos.com/upgrade
If you don't mind, if others from around the world bump this once in a while, it will stay visible for those who are not getting to the right page.

Bump
I don't want anyone else to faint....
Bump. Just keeping it visible.
EDIT: It is now (as of 06:00 PST) easier to get to the correct upgrade page, as a large upgrade button is now visible on the page you see if you select "Learn more" or "Get Logos5" from the home page. But you still have to notice and click on the "Upgrade" button to see the prices that take into consideration what you've already purchased.
