Pyramid Sector 85: Broker quotes seem off

Is anyone else finding brokers in Gurgaon are adding their own 'extra charges' on top of builder prices? I'm looking at Pyramid Infratech's new launch in Sector 85. Broker ne ₹10L upar quote kiya compared to direct builder se for a 3BHK. Mujhe lagta hai super area-carpet area ka difference bhi bahut zyada inflate karte hain. When dealing direct, how much negotiation room is truly there for stamp duty and registration costs? Should I just go direct, ya brokers ke paas koi real hidden deals hoti hain? What's your experience, especially around total acquisition cost?
