So I got to my TRU and was 6th in line. By the time they opened there was about 12 of us. We get inside and there's no Rosie's. Employee comes and says there's no Rosie's except one on hold. After waiting around 10 minutes for her to look, she finally finds a box in the back with 10 Rosalina's, 8 Toon Link's and Bowser's and two Sheik. They were also really strict only letting you buy one of the new Amiibo's. You couldn't get Toon Link and Rosalina.
But whatever. I managed to get mine at least.
Probably took her so long since she had to run to Target to get the box of Rosalina :p
