IRCTC I think it is one of the busy sites of India.Now a days it is required for everyone to open a account in IRCTC.It is founded in the year 1999 but it becomes popular after 2005.
I open a account on IRCTC for booking my train ticket.If your data speed is less then 2MBPS then you won’t able to open this site from 10.00A.m to 10.30A.m for tatkal booking.Otherwise it is a good site for booking your ticket by sitting in home.It charges extra 10 rupees if you are booked a ticket at counter.
Now IRCTC also started its online shopping business.You can also booked your flight ticket through this site.
