Mythic Map Pack Halo 3?

I really doubt that this will work out for me, but does anyone have an extra Halo 3 Mythic Map Pack code that they aren't going to use. Maybe you don't have Xbox Live or don't play online? If you feel generous, please email me rather than posting it on here. Zingo1109@yahoo.com Or you can AIM me. SN is zingo1109. Thanks.
