After upgrade of retail iWork 09 DVD it appeard on my Apple Store account I found my iWork 09 retail DVD, which I bought 4.5 years ago. After I installed it, Apple Store showed me that I've got an upgrade to version 13. Next, it appeared on my Apple Store account in purchases, after upgrade. Is it normal behaviour or it is a bug?
It's a normal behaviour so you can directly download the new Pages, Keynote &amp; Numbers on your new Macs (or new OSX installations).
