If you only need a single copy you are best suited buying from Microsoft directly.

If you need multiple copies you can work with a VAR (Value Added Reseller) to get better pricing.

CDW.com is the big name in VAR's but they have enormous turnover in staff. I try to build relationships with smaller VAR's. I like these guys: https://greenbeetech.com/ it's a small company with two guys running it who have decades of VAR experience (former CDW people).

Navigating the process of compliantly licensing Microsoft as you scale up is quite a job. Having a good partner to help your organization stay compliant is very valuable.

Why not go straight to the horses mouth? https://www.microsoft.com/en-us/store/b/windows

The statement that started the talk about resellers was:

> Similarly if you’re building it yourself you can buy for significantly less from a reseller, many of which are wholly legitimate.

The horses mouth charges $140+, which is significantly more than the $100 that was about.

Can confirm, that's the most straightforward way.
