Noida mein real negotiation sirf ek myth hai.

I work in real estate, but buying for myself, I'm finding builders like Blue Square Infrastructure LLP at Lagerstroemia Estate have fixed prices. Kya koi bata sakta hai kitna discount actually milta hai? Ya sirf spot discounts dikhaate hain? Total cost mein hidden charges bhi add ho jaate hain na? What's the real scene?
