I ended up going to four different Best Buys (I didnt purchase my MBP at any of these stores) and none of them would do it.
Store 1: "It's one or the other. This promotion also ended
yesterday but I could still trade the $150 gift card for the $200 off if you wanted"
Store 2: "This promotion is based on the store's discretion; we will not honor the promo along with the student discount. We don't even match Apple's education pricing here. Our playbook listed no expiration date on the promo though so it shouldn't expire for a while [when I asked about the previous store saying the promo ended]. I can trade the gift card for the $200 off if you want."
Store 3: "Yea sure no problem give me the SKU and I can do it." *gives SKU* "Ok just give me one second" *comes back* "My manager just said we can only do one or the other. The people in these pictures had their Best Buys override the system to enter it. The SKU for this gift card was just entered in the system today and because of such there is nothing I can do unfortunately.
Store 4: *rudely* "You don't get both. Stop trying to play the system."
Store 5 (further away store that I called on my way home): "Unfortunately we can't do anything because you didn't purchase the product here, however, if you go to
www.bestbuy.com/studentdeals and register your .EDU email address, you will receive a coupon for the $150 gift card + $200 off the laptop. It is based off the store's discretion though. Hope this helps."
Store 6 (another further away store that I called): "My manager says that yes, you were supposed to receive both the gift card and student discount. What we would have to do is process the laptop as a return, and then exchange it, in order to give you the gift card, because of paperwork. Unfortunately, since we haven't received any of the retina macbook pros in stock yet, it is not in our system so I can't process this. We also do not know when we will get stock, but probably 1-2 weeks."
Overall, not the best experience. I find it hilarious how some of the stores just flat out lie about the promotion. At least some people tried to be helpful. I also thought it was interesting what the lady from store #5 said about
www.bestbuy.com/studentdeals and registering your .edu email address. I did this but none of the coupons I received pertained to the $150 gift card + $200 off the laptop.

Maybe if some of you can register your .edu emails and let us know?
