Hurry: Wii U GameCube Controller Adapter is in stock at GameStop

The hard-to-find peripheral that enables you to use GameCube controllers to play Super Smash Bros. for Wii U is finally back in stock.

GameStop has the Wii U GameCube Controller Adapter on sale through its website. You can get it for $50 in a bundle with a GameCube controller. The standalone adapter, which typically sells for $20, is not in stock. The rarity of this item is a demonstration of just how dedicated the Smash Bros. community is to the four-player fighter. When combined, Smash Bros. for 3DS and Wii U was the sixth best-selling game at U.S. retailers last year.
