Go to gamestop (or wherever). Buy a powersaves portal with a powertag (should be included) for $25. With about 10 minutes on a computer you can have every single Zelda amiibo for free, just download the files off nfc bank. No $20 a piece amiibo bs.

Or, just buy some nfc tags and make them on your mobile phone. If it has nfc anyways. Bought 20 tags for cheap.
