Nick is selling to multiple buyers and had the hospital thing. If I were him, I would have waited to get money from everyone before even going to the P.O. to ship everything. No way of knowing if that's the route he took but it doesn't really matter. He's a guy with his own life and priorities, not a business. When you buy from forums and even sometimes from eBay, this is expected. At least he has been present on FB, here, and over the phone (my last "seller" here has yet to answer any calls or PM's. In comparison, Nick is THE SHIT!).
If the rod up your butt has a rod up it's butt, getting angry isn't gonna help. We've all forgotten cables, stands, etc in sessions or shows and this is no different. At least you got your mics already, plus no one could do anything with JUST windscreens. You'll get them, relax dude
