In the past I’ve managed to get some good deals on second hand software from EBay and actually found Microsoft and Macromedia’s licensing departments surprisingly helpful in helping to ensure that this is done correctly to allow for legally licensed software (Macromedia actually transferred a license for me).
Perhaps I took my eye of the ball but recently I bought a new version of Office 2010 Professional, which turned out to be counterfeit (I did get a full refund though) and today I excitedly opened a new (I was assured by the seller) version of Adobe Creative Studio CS 2/Macromedia 8 (old software but the cost of current versions is astronomical for a home user); all the CDs relating to Adobe Creative Studio CS2 are missing. As well as being very disappointed I’m now going to have to chase a refund and send it all back.
I shall certainly think twice in future!
