I recently attempted to do a trade with Woodsduck.
I say 'attempted' because he sent his stuff, I sent mine, then I got my stuff from him, and he... got to wait, and wait, while the postal service screwed him over.
The item in question somehow mysteriously managed to 'escape' its packaging, and go MIA. And only after some prodding did he agree on payment from me for his items.
Deals don't always go smooth, sometimes through no fault of our own, but Woodsduck handled this with great patience.
