Nintendo’s GameCube controller adapter for Wii U has proven to be a hot item, selling out basically everywhere and re-selling for up to $100 on eBay. If you didn’t snag one early, you might be hard pressed to do so now. According to retailer EB Games Canada, Nintendo is currently not making any more. Of course, this may be a region-specific situation, and we hope to see Nintendo get the adapter back in stock soon.
@Rynegod Haha, apparently Nintendo isn't making anymore at the moment 🙁
