Microsoft Office Professional
A couple or so years back my wife was doing the admin for a club I am in. She wanted a decent set of programmes and went on FleaBay to see what it would cost. She found a site where that nice Mr Microsoft was offering Microsoft Office Professional at a very, very reduced rate for academic use only. As she was also doing an ECDL and other courses at the local Tech college - well it calls itself a Uni now of course - she found she was eligible for all the things she would use it for.
No need to go to great lengths for rip off or fraudulent stuff as it is genuine with a proper licence and you get all the updates.
Can't think of the actual site but just go onto FleaBay or Tinterweb and you should find it.
