Nintendo has this serious problem with making to little of one product, the amiibo’s are one such typical disaster, the demand greatly outweighs the quantity of product available.
Just like the GameCube control pad adapter the didn’t manufacture as much as people wanted and with that, you have people charging anywhere from $40 to $140 for a product which was originally $20.
Mayflash and Kelux have released their own versions and whilst not the price the official control pad adapter was, they are a lot more reasonable than paying over $100, plus the 3rd part devices also work on the PC, you can view them below:
GameCube Controller Adapter for Wii U & PC USB – $39.99
KELUX Gamecube Controller Adapter for Wii U – $34.99
