Regretting my pre-launch decision in Sohna

Just got possession of my 2BHK in Badshahpur last month, from Tulip Infratech. Honestly, I'm regretting going for the pre-launch offer. The pricing seemed great then, but with all the PLC and floor rise charges that came up later, I'm not sure if it was even a real discount. Felt like a bait and switch, tbh. Did anyone else buy pre-launch in Sohna and feel like the 'early bird' advantage wasn't really there by the end? Or did I just mess up my calculations?
