New vs. Resale discounts in Noida Extension — what's the play?

Negotiating in Noida Extension feels impossible sometimes, especially with builders like Apex Group. I'm eyeing a 2BHK in Sector 28, around ₹70L. They quote 'no negotiation', but is that ever true? Are genuine spot discounts a thing here, or just marketing? Honestly, not sure what to believe. I'm wondering if secondary market deals offer better value. Can you actually negotiate more on resale properties in Greater Noida West compared to new launches? Prices are up 5-10%, but I'm looking for motivated sellers. What's your experience getting real discounts, new or resale?
