Just got my first order from them a few weeks back. Nice prompt service.
I wouldn't worry too much about getting pins, vials, etc. - I don't think there is anything inherently illegal about purchasing these. In fact, I've bought pins over the counter in my local pharmacy with no problem. (In U.S.) No prescription required. Of course, the prices were totally jive, and you could only buy 5 at a time, etc.
