I have a pool cue up on a Facebook group for sale. I guy messaged me and wants to do a trade. I want to trade him cues, but have never done a trade online like that. The guy doesn't have much up on his Facebook profile, so I am Leary. What if I mail him my cue and he never mails me his? Seems like an easy way to get scammed. What is the best way to make a trade that is safest?? Thanks
