Having lived in bigger cities like NYC and Atlanta, Binders isn't the best art store I've ever been to. It's good for Charlotte standards, mainly because it's pretty much the only legitimate art supply store in this city.
They've got a good supply of pens (which I geek out about) and paints, papers, etc. You should be able to find most of what you're looking for here.
The employees I interacted with were friendly. They were having register issues when I tried to check out, and they apologized profusely for the delay.
All in all a very good place to get art supplies.
