Newegg offers the refurbished Razer BlackWidow Ultimate 2014 Wired Elite Mechanical Gaming Keyboard for $69.99 with free shipping. That's $30 under the lowest total price we could find for a new keyboard. It features individually back-lit keys, on-the-fly macro recording, five extra macro keys, audio-out and mic-in jacks, and 1GHz key polling. Deal ends November 26. Note: A 90-day warranty applies, but it's unclear who backs it.
If you haven't yet, use Newegg’s Android app and pay using Google Wallet to cut it further to $54.99. (This discount can only be used once per account.)
