Just an FYI on Office 365 - although it retails at $99 for the home version, the most I have ever paid is $64. In fact, just yesterday
Amazon had a DoD on Office for $99 but including a $50 Amazon gift card, so net cost of $49. There are usually several offers throughout the year, and you can stack multiple years - right now I am paid up thru 2021.
It also comes with 1Tb of cloud storage for each user (up to 5), and 1 hour/month of Skype credit - which I do use sometimes - and you always have the most current version of the software. I am not a huge fan of the subscription model, but for around $5/month - I think I get good value out of it.
