Dead drops are in fact an excellent method of product distribution, but you need to be professional about it. If you search the forums I have a list of methods of using Dead Drops properly in a thread and PolyFront has some good leads on the subject too.That does not mean I am suggesting SR vendors use dead drops. It is overkill in this particular case. But for large quantities, it is hard to beat as a delivery method. Contrary to popular opinion, it can actually be done completely anonymously. I already elaborated elsewhere, so if you're interested you'll just have to do a search.
