What I wish I knew about Noida's pre-launch offers

Pre-launch deals are not always what they seem, I've learned that the hard way. Bohot time se rent de raha tha, finally Noida mein property dekh raha hoon. Arsh Group ka Sunpura project dekha tha, pre-launch offers kaafi attractive lage. But ab lagta hai actual discount nahi milta, just hype hai. Kya early-bird pricing mein sach mein koi real benefit hota hai, ya just marketing gimmick hai?
