Builder ka 'all-inclusive' price tag pura jhoot hai Noida Ext mein

Yeh builders ka 'all-inclusive' package kitna sach hota hai? I work in this line, but for my own 3BHK in Sector 150, I'm seeing so many hidden costs beyond basic PLC/parking. What are the *real* surprise charges that pop up at possession? Super area vs carpet area games toh chalte hi rehte hain. Amaroo Group mein kya scene hai?
