Oak Park, IL
Whenever possible, I've gone to Central Camera for purchases and advice since the late 1970's when I was a student. Unlike the chains such as Ritz/Wolf, they employ people who love photography and know a lot about it. And if you are ever lucky enough to experience shopping in their little store it is a throwback to the camera stores that used to surround the loop area and that catered to the pros and amateurs alike! But if you must get a camera via phone order but still live in Chicago, they will deliver it to your door -- FREE! Their on-line service is great too. I purchased a scanner from them a couple of years ago that way.
