This location is set up more to be a print centre than an office supply store. However, that doesn't mean they don't have what you need. I've gone in a couple of times here with what seemed to be odd-ball requests and they're always had what I needed.
This is a handy location too being right next to the Reference Library. If you're trying to do some research at the library and have forgotten a pen or something, you can just run across the street.
