my trial has run out and i'm going to buy CS6 design standard, I have found it on Amazon for a little cheaper than I can get it from here. I am wondering if there is a reason why I shouldn't order it from amazon, will it not be in my download history on my adobe account? Will I still be able to get all the Adobe support?
Just ensure that you're buying genuine software from a reputed buyer.
Note that there is a diference in buying from Amazon.com and from the Amazon Marketplace. In the Amazon marketplace, users can buy/sell goods, and Amazon is not the seller, just the facilitator.
So it would be a good idea to check if the seller is Amazon.com. Look for the following: "Ships from and sold by Amazon.com."
North America
Europe, Middle East and Africa
Asia Pacific
