OOH! OOH! Hey Crashed! Hey Ruthless!

I got a new computer and it came with some digital game codes that I have no interest in. I would like to give them away here on the o-deck. What's the least disruptive, fairest, most legal, least likely to get me chastised way of going about it?

I can ask who wants them and post them in a reply. I can just post them in the body of the post and let the first person to see them find them. I can ask for bribes. I can do whatever people recommend. Just let me know.
