Update: Code is expired, sorry!

You’ve probably got a drawer full of old microUSB cables that are becoming less and less useful as USB-C slowly takes over the world. But instead of throwing them out or outright replacing them, these ultra-affordable adapters effectively turn them into USB-C cords. Get three of them for $4 with code 2QBQTI53.
