NKV Groups deals: My broker ki gappein?

Spot discounts are often a mirage, especially in Gurgaon's current market. Builders like NKV Groups in Sector 7 won't budge much on listed prices now. My broker says they're offering 'limited period' deals, but I doubt it. Is anyone getting real concessions or just PLCs waived? Kya negotiation possible hai, ya only through brokers?
