Salarpuria Sattva's 'fixed price' is just marketing.

₹1.8 Cr for a 3BHK at Salarpuria Sattva near Ameerpet feels non-negotiable. I work in real estate, but even I'm struggling to get any movement. They're pushing construction-linked plans. Should I push for a spot discount or leverage payment terms? Is their 'fixed price' policy just a facade in Hyderabad?
