Hey Twisted
Supposedly yes the coin is only for those who reserve on the day of the event. Day One as you put it is confusing because there were 2 days of this event, today and last Wednesday, making today actually day 2.
My thought is this, when we go to pick up our pre-orders, how are they going to know who ordered during smashfest and who didn't? Are they going to check the time and date on everyone's receipt and only give it out to people based on that? I have a hunch that will be too much work and they'll just give them out to whoever show up on release day with a pre-order receipt.
But I don't think every Best Buy store will get these as bonuses. Just the ones that hosted Smashfests.
This is all pretty much speculation by the way.
