Since the Surface is not a hot seller at the moment, Microsoft won't be able to save any money by spreading out orders for the chassis to multiple suppliers, and trying to negotiate a more favorable price amongst them.

Back in June, the Microsoft Surface Pro 3 was launched. The slate is being marketed as a replacement for the laptop, able to handle any work related tasks, while also allowing users to play games, browse the internet and check their social networks. That makes the slab perfect for business executives and students alike. Just last week, Microsoft expanded the distribution of the Surface Pro 3 to 25 new markets.
