Pune property negotiation is mostly a myth

Honestly, I thought buying a flat in Pune would be simpler, but it's a jungle out there. I'm looking at a 2BHK, maybe around Amanora Park Town or even Baner, and the pricing is just... confusing. My budget is around ₹90L, but the quoted prices for a decent 2BHK are often higher. So, first thing, does price negotiation actually work with builders like Arun Sheth Properties? People say you can knock off 2-3%, but I wonder if there's more room, especially if it's a ready-to-move unit. What's the realistic percentage one can expect? Also, pre-launch offers ka kya scene hai? Is early-bird really a discount, ya bas marketing hype? Not sure if it's worth the risk of delays for a few lakhs. Any experiences?
