Techsoup.org is a great place to buy software if you work for a nonprofit agency. For instance, MS Office 2011 for Macs is $23. See http://home.techsoup.org/pages/product.aspx?cat=techsoup global catalog&category=&id=ls-3013 NOTE: I do not work for Techsoup, and do not benefit in any way from sales by them. I am not selling anything here. Techsoup is a very well-regarded source of tech info and software for nonprofit organizations, and I am sharing this information about them because I've noted several posts from people regarding MS Office for OS X.
