Is pre-launch pricing for Lion Infra in Sector 25 actually a good deal?

Everyone glorifies early-bird discounts but after stamp duty, PLC, and those 'other charges,' I'm not seeing the real savings. I just bought with Lion Infra in Sector 25. It feels like the advertised discount just covers the hidden costs. Change my mind, are genuine pre-launch deals still possible in Gurgaon for investors?
