Good to see. The Apple Business discount in USA is likely more for those that can reach the threshold.
I'm not sure how big actually the business discount is, I've heard it is between 4-6%, $500 off on configurations below $10,000 is actually pretty good/similar discount.
Don't forget that B&H offers its own credit card, after instant approval card can be used right away, that "eliminates" tax. This for some, is additional savings of over 6%. Another advantage of buying from them, is that some configurations are already in stock and can be picked up the same day. No need to wait over 2 weeks, as it looks like Mac Pros are being delayed: https://www.macrumors.com/2020/02/12/new-mac-pro-shipping-delays/
