My experience with CompUSA has always been pretty good. If you are in their business sales program the prices are pretty good, comparable to CDW. There's also a store a few miles from our main office. If we don't have something on hand, say a sound card that needed to go in a computer at another location, I can call our rep. who will pull the item off the shelf and ring it up. Then the technician who's on their way to do the job can stop by and exchange my signed purchase order for the gear. It's also nice to be able to take stuff back to the store if you order online but don't want to deal with the hassle of shipping it back and getting a return authorization, especially since I'm going there a couple times a month anyways.
