Office 2010 where to buy

[fazersharp]

Could she take a computer from her work or ask for a laptop?

Its all desktops and anyway she don't like working on laptops cause all the buttons are in funny places  :wall

we will look into the home use link but dont think that will be an option

So back to square one -- looking to buy a copy, but dont quite understand the ones for sale on ebay that say things like it was not reinstalled when the computers OS was reinstalled
