Got it last month for about £12-15. They gave us the "Enterprise 2007" edition which has the full suite of Office products and works with previous versions (essential with some of the vintage software the MoD still use). I simply did a search on the Defence Intranet, found the link, and filled in the form. A quick e-mail at home followed to confirm ID then my Disk arrived within a week. Fantastic VFM!
