I heard from a WWE source several weeks back that WWE Tag Team Champions The New Day were doing great merchandise numbers, thanks to the sales from their t-shirts and socks. Apparently Xavier Woods' 'UpUpDownDown' gear has sold well also.
This is probably why WWE released a bunch of new merchandise for the group on Monday. Kofi Kingston noted on Twitter that the unicorn horns sold out in just 5 hours. He tweeted:
They sold out in less than 5 hours! We will let you know when they're back online. They WILL be at shows though. ???? https://t.co/vW78W3kq9N— Kofi Kingston (@TrueKofi) December 8, 2015
