I've sold, bought or traded at least a dozen bows on this site and have never been burned. Nor have I burned anyone else. I always offer a money back guarantee if the buyer doesn't like what I'm selling for any reason.
On trades, we've usually mailed at the same time. When I buy, I send the money, then the seller sends the bow. I do it the same way when I sell. Likewise on lesser items. I have had two folks tell me the check was in the mail when it wasn't. Luckily, in those instances I was holding the item until payment was received. Quite rare, but these weren't new members. Regardless, it won't stop me from continuing to trade via this site. 99.9% of the folks on this site are honest. Can't do any better than that.
