The problem with buying used copies is that you cannot be sure of the quality of the disks themselves, whether they are actually genuine, and whether they contain documentation and (where applicable) key codes. Always make sure that you have recourse for any such purchase.
On the other hand, if you can buy a new copy of an superseded application from a reputable source on clearance, this is a great way to save money, since most versions of an application are backward compatible, and many new features on the latest version may be fluff and the prior version may have all the functionality that you need.
Whereof one cannot speak, thereof one should be silent.
