I've bought and sold on GunBroker for some time. Recently I sold two rifles on GunBroker and both buyers backed out. There was no way to speak to an actual human on GunBroker about these failed sales, so I was still charged for them. Their complete lack of caring about sellers has made me think twice about listing a firearm there again.
