I recently shipped a rifle from my FFL to someone 1500 miles away for a total cost $56. There is no FFL transfer fee for seller, only the buyer at their FFL upon receiving the firearm.
I do believe everyone has the right to do what they want with their stuff. I also believe it would be common courtesy to let people you are dealing with know that you are no longer interested in dealing with them rather than deleting your ad. Simple text or PM takes a few seconds to type.
