I have spent literally tens of thousands of dollars in supplying my small retail store. Suffice it to say, a new paradigm exists in wholesale adult; because adult is just a small part of what I do, my analysis is that I receive better service, pricing and broad availability (and can buy in extremely cost-effective small portions) than from one old ways of doing business. And not for nothing -- i have been at this 22 years -- and am determined to still carry adult but am not an adult store. You see my point. Other similar sites have much more the feel of retail, consumer sites. ADM is a bare bones no-BS operation, mostly populated by small-time San Fern jobbers existing on couple-bucks-over type sales, streamlined and assumably universally despised by old-school adult vendors for their efficiency (and don't get me started on the value of Priority Mail these days).
ADM is a paragon of efficiency for me. I stand by them singularly.
