I have 2x 1 month Xbox Gamepass Ultimate thingies. The little cardboard coupon thing with the scratch off code (unscratched of course). Came with 8bitdo controllers.

I have no use for them myself.
Best way to sell them?
Looking it up online it seems Xbox don't permit the sale of these code things, against their ToS.
I wanted to sell them on Ebay but I don't want them to flag it to Ebay and then Ebay to crack down on my account.
Also what's to stop some faggot buyer using the code and then complaining that the code was already used?

Is there any way to get any money out of these? The price of 1 month of Game Pass Ultimate is the equivalent of 20-30 burgerbux in my cunt, would be nice if I could sell them.
