Pre-launch discounts in Noida are a total scam, change my mind.

₹78 lakh for a pre-launch 2BHK in Sector 107 sounds good, but I'm worried about builder delays. ATS ka project hai, they say early bird discount hai. But I hear stories about construction-linked plans draining people. Is it really worth the risk for a few lakhs discount? My parents are saying wait for RTM. Kya lagta hai?
