Stop Mountain items

Please stop giving mountain items as a reward.  I have watched the marketplace all day long and there's always an average of thirteen to fourteen out of twenty cities that have nothing but mountain expansion items.  Everyone in my club has stated the same thing.  Surely there could be a filter that shows when someone has expanded everything in mountain or even beach that those stop showing up. 

With the new materials storage, there's going to be less people posting anything good. It would be nice if you would create a war storage, too. That would allow better separation of items.
