The lights are on
In August, Nintendo began offering a gold Wii nunchuk as part of the Club Nintendo Rewards Program. It quickly sold out. It was offered again on November 26 and sold out. Starting next year, however, you'll get another chance to grab one. "The Gold Nunchuk will return to #ClubNintendo after the New Year. Start saving your Coins!" Nintendo said on Twitter.
The controller costs 900 coins, according to the product page on Nintendo's website.
