Is a 'spot discount' in Faridabad truly a deal?

Sector 35 – I'm finally done with renting, trying to build equity. Goyal Estate Agency showed me some 3BHKs around ₹80L. They're pushing a "spot discount" but it feels like a gimmick. Does anyone know how much real negotiation room there is, especially with builders like Omaxe or BPTP? Is this just a tactic?
