In my opinion Domestic Shipping has the following advantages over International Shipping:* Quicker Delivery* More secure as there's no customs* Less possible damage on the package from being handled in multiple installations* Cheaper cost (although this could admittedly be negated by higher product cost)Now this is obviously in the context of illegal drugs. The day drugs get legalized (if that ever happens) the benefits of International would most likely in many cases outweigh Domestic as large corporations would take over the distribution similar to how the tobacco industry works.
