Did you try Google? I found several from unfamilier businesses. Who ever you decide to buy from make sure you can get a refund in case you can't register it with Adobe. You won't be able to transfer the licence or upgrade or get updates and support if you don't buy from an authorized seller. Adobe has a list of authorized sellers. CS6 might be expensive but at least you have the option of future upgrading along with support and updates.
