It's crazy how popular amiibo's are in the United States! People are lining up for these things when they come out, and for what? I have maybe around 12 of them and have barely used them at all. I guess they just look cool.
Either way, you can get a Mario, Bowser, Peach, Link, etc, pretty easily! However, when you start talking about Fox, Captain Falcon, Robin, etc...you'll never find them...unless you live in Austrailia.
