Noida Extension flat purchase: Anyone gone direct to builder?

Honestly, I thought I knew all the tricks being in real estate, but buying my own flat in Noida Extension is making me pull my hair out. Especially with these brokers for projects like Kkay in Sector 84. They promise big spot discounts and better terms, but jab final negotiation ki baat aati hai, it's always 'builder won't budge'. Is it even worth engaging with them? Or should I just directly approach the builder for a 2BHK? Do direct buyers actually get better pricing or concessions?
