If you want to purchase Cubase then either you can purchase and download from online official sites, this will cost less in price but will cost more in downloading data. So if you have a broadband then you can purchase online starting from approx. Rs. 8000+ (for Cubase Element). If you want to buy offline then there are many sites but trusted like Bajao and SudipAudio etc. They will send it to you by DVD or any other medium.
