It could seem strange that some of the decorations’ prices increase as you continue to buy more of the same items. The main reason for this is that the more items you buy, the more sophisticated your farm decoration becomes. As an example, if you buy several fences you can create more elegant patterns around your farm, which makes it even more unique and special. The same happens with some of the premium seasonal decorations. Some players can afford only a few and others who are willing to invest more can bring their farm decoration to a whole new level!
Decorating your farm will not only help you earn some diamonds or experience points by reaching certain achievements, it also may impact the amount of followers you have in a positive way 🙂
