How do I remove the Fair Offer Policy from my posts?

Every time you post an Offer, there is a checkbox on the new post form that asks if you want to use the Fair Offer policy. Simply uncheck it the next time you post to indicate that you don't want to use the Fair Offer policy on that post.

Old posts can't be edited to remove the Fair Offer Policy - see the help page on editing posts for more details about this.
