Don't buy an amibo ya'll
I honestly wouldn't have a problem with amiibos if nintendo didn't continue the ridiculous practice of making them all limited runs.
Nintendo doesn't even bother selling the in game items the amiibos unlock as DLC.
It would seem they actively encourage the scalping people do online with these toys.
I wanted to get the BOTW ones but I'm not gonna sit on a site refreshing the page all day in hopes to get a $15 - $20 toy that unlocks an in game sword.
If you have an android phone with nfc you don't even need those cards. There are already apps that let you use the phone itself as an amiibo.
I'm on iPhone so I think I'll end up just buying the cards from somewhere online.
