Salarpuria Sattva discounts are a mirage

Salarpuria Sattva Karmanghat mein koi real spot discount milta hai kya? Builder bolta hai no negotiation, but agents say kuch ho jayega. Kids moved out, so I'm looking for a smaller 2BHK, around 80-90L budget. Resale mein better deal milega ya new construction hi dekhein? Not sure how much builders actually budge.
