I found an error on the cost of materials to buy a warehouse. It should cost 358.81 materials, instead of 3558.81 because I can actually buy the warehouse with 358 materials. Sorry for my english. I hand you the picture: http://puu.sh/gZGyn/2f33c93491.png
Check on the lower right part of your screen, you have 10x button pressed. So it gives you the cost of the next 10 Warehouses ! Since you can buy at least one warehouse buy is enabled though!
