I actually did this business. The short answer is the vendor landscape is super-varied, and that means you have a ton of different companies to deal with, each of whom tends to be small and doesn't have a very good vendor support operation. Since we didn't want to carry inventory we did drop shipping, but the margins were not ideal. It was possible, but the realities of the business, at least several years ago, were difficult operationally. I could talk to you in detail about it if you like.
