The Exchange is really cool all around. I've been visiting all of them since I first moved to Pittsburgh in 2010. My first experience was being a broke college student and selling all of my old CD's and DVDs. I was sad to get rid of some classics like Superbad and Pineapple Express but a girl needed some cash!
Fast forward to 6 years later and I still head to the exchange to buy movies. They have a great collection. You can always call them and see if movie is in stock. If not, they can even tell you what Exchange location does have it.
Its cool to have an option like this in the city. Where I'm from, places like this dont even exist anymore. lol
