Just figured I'd make a thread about it for all those who might've qualified for this, but BestBuy just sent out the emails earlier today for the promotional code for those of us who qualified during the "preorder 2 of these games and get a pin set" promo way back in June.
Already got mine ordered - the promo code takes off the $75 charge and makes them free.
Figured I'd mention it in case it somehow got forgotten by y'all or sent to spam.
BestBuy - Mario Maker 7-Pin Set
