Edit: OP clarified that he's hoping that someone doesn't need their keys anymore (and hasn't added them to their B.Net account yet) - he is not looking into *buying* keys. Keep in mind everyone that selling keys is illegal (and also not a good idea to buy since you might be blocked out of B.Net any time).
