During the last Nintendo Direct, Nintendo revealed a new line of Amiibo. It was also announced that some would be vendor exclusive, without further explanation. We learned today that Best Buy has one such exclusive deal.
The Majora's Mask Link Amiibo and Bayonetta Player 2 Amiibo are Best Buy exclusive. The unfortunate part is, the Link Amiibo sold out of pre-orders before Best Buy even posted their press release about it. They'll most likely restock after the initial, however. They hit shelves June 23.
Bayonetta Player 2 releases at Best Buy July 21 and is still available. The other Amiibo not listed, but announced during the last Nintendo Direct will be available July 21.
