Ahh too late, I forgot about GameStop, might just do that instore as well tomorrow. Before anyone replied I got one a Wal-Mart, oh well hopefully I can cancel.
Yeah that seems to be the case. Someone hit the cancel all preorder button, since almost no one seems to still have a preorder at Toys R Us at the moment from what I'm reading. Even some Disney Infinite preorders were cancelled. So I doubt it's a amiibo specific issue. Hopefully tomorrow morning this will all have passed like a bad dream and they reinstate the preorders.
However since preorders don't really meaning anything, I got both Rosalina & Lucario on Amazon Germany. My safeguard if nothing goes my way.
Edit: Switched it to Amazon France, 10 Euros cheaper on shipping.
