People do not like uncertainty. It's the same reason why it seems people on this board are willing to spend 20 for a foreign amiibo despite having ordered an US amiibo as well.
Seems they've limited it or at least to me. I ordered one months ago and it wouldn't let me order another one unless I logged out and used a new shipping and billing address
Maybe, I don't think the bundle is supposed to be rare though. I think its just a convenient way to get the game + an amiibo for amiibo mode sorta like how you could buy MK8 with random accessories
New Here but in for 1. Better safe than sorry and 3.50 shipping isn't the end of the world. There's a good chance we might be able to web to store a pit order though.
