PowerA Wireless Controller for Nintendo Switch (Gray) | $17 | Amazon
Update: Sold out.
Note: This was very recently on sale for $34, but the price has been slashed down to $17. This price is an all-time low for this product.
If you suddenly find yourself in need of extra controllers for your Super Smash Bros. parties, PowerA’s Gamecube-style wireless controller is down to $17 for the grey version, which is a dollar off its all-time low. It’s laid out exactly like the controller of yore, and feels like a nice jolt of nostalgia, but it’s also wireless, which is awesome.
