I want to upgrade my older PSE version to current PSE version. How?

If you own any older PSE version, then instead of buying a full version, you can upgrade to current version (as upgrade will be less expensive than buying Full version). For upgrading, you can visit: http://tinyurl.com/9pgrhte.

For example, I have PSE4 installed on my system. Now I want to have the current PSE version (which currently is PSE11). If I am going to buy a full version, it will cost me $99.99 as shown below (snapshots taken from link mentioned above and may subject to change)

Instead if I do a upgrade it will just cost me $79.99 as shown below:

Please leave your comments if you have any queries.
