The very limited-edition Golden Nunchuk is back in stock at Club Nintendo, going for 900 coins. Last time this nunchuk was offered it sold out very quickly so if you’re keen on grabbing it from the coins you earned through purchasing your Wii U, you better hurry. If a golden nunchuk isn’t really your thing, you can always check out the other rewards and redeem them before your points expire. I’d personally find it hard to want to use the golden nunchuk since Nintendo isn’t offering a golden Wii remote to go along with it.
