Their site actually redirects direct pricing link page to plans page. On the plans/pricing features page, click on "purchase now" & in next page you will see the option to fill all the details & there at the bottom you can see actual plan charges in drop down options.
Okay, so that's where the plan details are.
The individual plan D is 2 TB for Rs. 199. Assuming that's Rs. 199 for a year for 2 TBs, I'd say that's a good option, for storing non-important stuff. A 2 TB HDD would cost around 5-6k.
