That is correct for OBO however most (not all) would not see an add for X amount and try to offer 2k less. OBO Typically means for the right opportunity (cash, pick up, BFF) you would be willing to come down a few hundred. A few thousand would be an insult in my opinion. Your game looks pretty nice, remember that higher end titles Will take longer to move as that market has fewer opportunities. Not to disagree with others but at least as of recent Creeches have quickly grown in popularity and interest. In my opinion 6 would be the floor for your machine. 4k would be a Trashed game which your machine does not appear to be. Better pictures and let it simmer for awhile, you will find a happy buyer in time. Good luck!!
