Redeeming Codes

I am curious if the site just closed down for the redeeming sites for weapon skin codes? Bought the Nerf AR over a year ago and just re-found the code that came with it, but go to halowaypoint.com/redeem and the site can not be found. I figure now that the game is released might as well finally punch in the code since I found it when clearing out my place before moving. Anyone else have that issue?
