On the Adobe home page for your country, enter Creative Suite in the Search field. Then you'll land on a page that has a Buy Now link for Creative Suite which itself leads to a new page containing a Buy link for CS6.
Hello, Buck, as per Samoreen's directions, (besides searching for Photoshop CS6 if you do not want a suite either) once you see the buy: full, text, you can click on the "full" to select upgrade, it is not intuitive at all.
Here's a quick and dirty guide to getting the upgrade to CS6 if you do not want the cloud subscription.
Scroll down to Photoshop.
Click "Buy" Ignore the $699 for now.
Full version will be the default. Click on "Full",and select "Upgrade" and, then follow by selection what version you own, the platform and language.
The total will be $199, Proceed to checkout.
Thanks for your help people.
Have now managed to buy my upgrade .
Now if I can only get it to work properly I will be a very happy man.
