Back in 2016, Nintendo released the Super Smash Bros. Retro amiibo 3-Pack exclusively at GameStop locations in North America.
The 3-Pack includes a R.O.B. amiibo, Mr. Game & Watch amiibo, and Duck Hunt amiibo. All three were sold together and never separately in North America, and have been exclusive to GameStop ever since 2016.
Today, Best Buy has started offering the same 3-Pack after two years it was released. In other words, GameStop’s exclusivity deal with Nintendo for the Retro 3-Pack is over.
