What are my options for getting MS Office for myself?

If you are not needing to be part of team/organization that is shares information and documents, then you will want to consider one of the many personal options. The first is to purchase a perpetual license that can only be put on one machine, period. Your options here are Home & Student $150 or Home & Business $230. The primary difference is that Outlook comes with the Home & Business version. When purchasing one of these two packages you are purchasing the current version of the software that does not have an upgrade path to new version and can only be installed on one machine. The positive point is that you are acquiring at a fixed cost. If you do not upgrade your MS Office with each new version and if you have multiple machines that you want to put it on then you may find that the subscription service of Office 365 is a better option.

On the personal side you have two choices, either a Personal Subscription $70/year or a Home Subscription $100/year.
