I did do that, which is how I was able to get the replacement. My frustration is after all of this headache, all the calls, emails, etc. I still have to wait for a replacement, and said replacement is in stock for same day purchase at said store. But for one reason or another they can't just give me one out of the shelf and be done with me. Rather they have to give me I don't know what. Its one thing if they gave me a previous model or something that they don't carry anymore. I know im being a selfish prick at this point, but 3 weeks of my life have been wasted chasing after this crap. At this point Id have been better off just going to the store, picking up a 16 gb M2 Air and throwing the 2017 MacBook Pro in the garbage and moving on with my life rather than emailing, calling and *gasp* asking a company stand by their products.
Usually if they are issuing a replacement device, it comes from a completely separate pool of inventory, not from retail stock. The same thing goes for replacement iPhones and iPads. The other consideration is that in most cases, replacement stock for laptops (regardless of brand) has to come from the manufacturer. Best Buy does things differently under GSP in that they just issue you in-store credit for the original purchase price, which you can then put towards a new device.
