The listing, New Sealed! Photoshop CS I Upgrade - Free US and Canadian Shipping has ended.
This is a new sealed Photoshop CS I upgrade. Another keeper for those rare software collectors.
Anyway if you have any previous version of Photoshop lying around you can put in the serial number during install and the upgrade should work. Hopefully the person who wins my Photoshop 5.5 listing, http://www.listia.com/auction/1553644, can also do the same thing. I believe he/she will be.
With CS1 you can then climb in Photoshop upgrades all the way to CS 4 which costs about $175, see here: http://bit.ly/i0kmux although they are scarce!.
Free US and Canadian shipping.
