OK, then what's the question. Since you went to the school I'm sure you know if the store is legitimate or not.
If it is a good deal and you're looking to pick it up then pick it up. If you have an issue I'm sure they can refund you. No one here can offer anything more than that...
I did not. But I did speak with someone at the UCLA store and they said I just would need to bring in the laptop for inspection by someone at the store before purchasing. I decided to wait for 2020 13’’... which I might just buy from Costco with a Costco visa (which gets me a 4 year warranty w/o having to buy Apple care).
Late to the party, but I've purchased AppleCare+ from my university bookstore (which is, like UCLA's, an authorized Apple retailer), and it's no different from buying from Apple (just less expensive).
