CDW is a terrible company and provides no added value in the modern age of technology purchasing. Before the big market places existed for tech hardware - Amazon, Newegg, etc. CDW added value as a one-stop shop for purchasing. But they're no longer relevant and the only thing they do is charge more and add headache. I know they've entered the service market and I have less experience with that side of their business, but the limited experience I have had, has also been bad.
I've worked for three organizations where CDW had a presence from before I arrived. They get their tentacles in with vendor agreements and contracts that make it difficult to break away from them. I won't get in to the details of the multitude of negative experiences I've had with them, but it's been pretty much every time I've dealt with them. Ohh and customer service is awful.
CDW exists today because of inertia. That and there are still some old-timers in the industry stuck in their ways. They provide no value added.
