Game add on code for how much sell?

I bought an xbox one some time ago and there was a code with add ons for fortnite battle royale at (2,000 V-Bucks, legendary outfit "renegade spider rider" and 2 other outfit styles)

I don't play fortnite and therefore don't need the code. A friend told me that I could sell the code on eBay. To those who are familiar with fortnite: how much would you pay for it or for how much euro would you sell it?

Take a look at how much other salespeople charge for it and use it as a guide.

Thanks

Better leave it off with the sale, it can get you in trouble

What does that mean now

That you are not authorized to sell the code and that it is actually a criminal offense
