offcourse, here is also for sale http://nova.eplati.com/index.php?route=product/product&product_id=115 and here http://www.g2play.net/store/Call-of-Duty-Ghosts-Steam-Key.html but keys not available now. You will get keys one day before release. So be quiet scammer!
looks suspicious, i must say. 3 of your 4 rep are from 0/0 guys, all within the last 24h. and ghosts keys? for this price? i don't think so. well, maybe you should tell us, where they are from. with the information i see here, i definitely wouldn't buy from you.
At the moment there are no keys for ghost...
NO ONE has keys for this game...
:P
