I think a lot of this applies to all trades online. If you're wanting to make a deal, you better ship first or the other person will back out; they should anyway. Also, if you aren't that well known, don't expect people to be so willing, keep plugging yourself away at what you want and sooner or later someone will take a chance because they want what you have and have what you want.
I've so far completed one trade through online, and have two more lining up. People just have given me a chance despite having no history. However, I've been lucky enough to want from people with good BOIs so I feel comfortable shipping first and have done so already. It's a little nerve racking, but once you get the tracking number you feel a sigh of relief and then anxiously await the package.![]()
