Since this is the time for Pujas, the agents ( be it IRCTC approved or just simple ones) charge somewhat more amount than they usually do!
I myself had enquired to book a Tatkal ticket for Ypr Howrah express between 8th-10th of Oct, 2010. I was told that I had to pay 300(Tatkal Amount)+500 (Agent Fee) for reservation into any AC Class (II Tier or III Tier).
