Use LibreOffice instead
LibreOffice is in many respects equal to or better than MS Office and for the typical home user with only basic documents and simple spreadsheets is more than good enough. (LO is also better than MS Office for reading a number of MS Office documents as MSO often seems to have difficulty reading documents from different versions.)
Given that the price of LibreOffice is far lower than MS Office, for most users LibreOffice is by far the better choice.
