How do you get the Xbox one skin in fortnite?

I wanted to ask how to get the Xbox one skin in Fortnite. I have an Xbox one and I have Xbox Gold too. What do I have to do then?

I've seen something like that in the media market, as a voucher card, at all vouchers of the gaming department and at the cash register.

Hmm, I thought it was free

It was only available in the Fortnite X-Box One Bundle.

If you had the X box before or did not buy with the bundle, you will not get the skin either.

You can, however, buy cdkeys.com or such code then you get it.

You know, I do not know about the game, I just saw a coupon card at the cash register. I personally hate even Fortnite, because of the hype.
