Doing that, I know what I'm getting, that it is 100% legal, and I don't have to worry about asking Microsoft for support (in their forums), as my account would show that I purchased the product directly from them. Perhaps my best option - if I want to upgrade - is to get a sub to 365 Personal, which is $70/yr.

On Ebay, I found some sellers offering license keys but not the original installation DVD only a 'backup copy'. When I checked a couple of the sellers on Amazon, it wasn't so clear as to what I would be getting, except that the package included a valid license so the product can be activated. They supposedly send you a link to download the software. One such item on Amazon states that the license key is in a sealed package, but without the installation DVD. How would someone go about obtaining a license key without the installation DVD? Doesn't everything always come in a sealed package? But I am a bit suspicious of anyone offering a license key only. I found several sellers on Amazon, and some on Ebay offering product key only, with a dl link for the software. Next issue is how to purchase Office 2016 pro.

Sure, there are some nice new features to 2016 compared to 2010, but would I use them? I read the info at the link you provided.
