www.techsoup.org I don't know if its been mentioned for awhile. Not for profits and libraries can get very cheap manufacturer donated software from the site. For instance, Windows 8 upgrade for 14 dollars. Office 2010 or 2013 Professional for 32 dollars. Quickbooks Premiere one seat for 45 dollars. So, if you work for one of the above, or maintain computers for some like I do, you might want to alert potential buyers.
