> I suspect a bulk educational purchase of any laptop would get a discount, though I'm not sure how it would compare to Apple's
For straight-up education, https://www.lenovo.com/us/en/landingpage/students-and-teachers/ says 5%, as compared to apple's ~15% (closer to 17% on this one). But on their site, that IdeaPad looks to be $380, which means that with the "discount" you still don't get close to Best Buy's pricing anyway. As you say, MSRP is fake, but that still looks like a clearance price to me.
