I have to say that I agree with Shaun on this one. For the most part if you have been on RCM for a while you know who has been around long enough to make a judgement call. I have had no problems dealing with RCM brothers, and outside of here I have requested phone confirmations to kind of size up who it is that I am dealing with. Usually no one will ship until they receive payment for the item. In the case of a trade I would base that on conversation with the other party, and there should be no reason that both cannot ship at the same time. Good luck with that man.
