Salarpuria Sattva Rajendranagar pricing: Is negotiation possible?

Salarpuria Sattva 2BHK pricing in Rajendranagar feels really firm. We're downsizing after the kids moved out, want something low-maintenance. How much negotiation room is realistic? Are spot discounts just marketing? What hidden charges should I watch for before possession? My budget's around ₹1.2Cr. Any experiences?
