MS OFFICE 2013 (Family - SBE) available for €199 extra (I need Word and Excel).
We have used Open Office/Apache products on our machines for several years. As good as MS and free. Not quite as many bells and whistles, mostly not needed anyway.
https://www.openoffice.org/ If you have concerns regarding compatibility of file formats, there are solutions to that. When I send documents out I save and send them as .pdf. If the recipients need to work on them you can save and send in MS Office format.
I have nothing against MS other than their market domination, and the cost of it would be borne by my clients anyway if I chose to bill it to them, but I like supporting other providers than those who dominate.
