I love seeing items disappear from shelves as I buy them in a shop. It was really a nice touch. It also shows us that shop inventories are handled in a different way than they were in past games. Previously, everything you could buy was in a hidden chest and the shelves were just stocked with decorations. Now, if I see something in a shop, I know I can buy it. I'll be interested to see how that works mechanically when the Creation Kit is out.
