I bought MS Office 2007 Home and Student over a year ago. I need to get MS Access but it sells close to $200 by itself. I could get Office Professional for only $80 but the Home and Student version that I bought has 3 licenses, of which I'm not using 2. Is it possible to sell the 3 licenses and get the version I need? Or is it possible to just add Access for very cheap? What's the best way to do this?
