Pre-launch 'deals' are a trap in Greater Noida, change my mind.

₹95 lakh for a 3BHK in Sector 115 seems okay on paper, but I'm really trying to understand the *actual* total cost. I'm currently in a 2BHK and looking to upgrade to a bigger place, maybe even a small villa. Already have a home loan so I'm hyper-focused on the total acquisition cost this time. Are these pre-launch 'discounts' from builders like CPA Developers actually worth it? Or do they just bake in all the future increases anyway? Seems like a marketing gimmick tbh. What's been your experience with early-bird offers in Greater Noida? Do they really save you money in the long run, or is it better to wait a bit? Also, what hidden charges should I watch out for that only appear at possession? I've heard stories about unexpected PLC, maintenance deposits, or even society formation fees that aren't clear upfront. Trying to budget properly. Any specific Greater Noida traps to avoid?
