I am thinking of what is the best way to purchase adobe license (look for web premium pack), so that it wont burden a company expenses. My option as below: 1. Purchase from adobe store 2. Rent adobe licence from adobe store 3. Purchase old version CS2 - CS3 with Azamon or ebay, then upgrade it to CS5. The price is much more cheaper to purchase old version, but is CS2 or CS3 allow direct upgrade it to CS5? Do you any other better option?
