Rajkot pre-launch offers: are they real discounts?

150 Feet Ring Road — been looking at properties there, especially with the airport nearby. I'm based in Dubai, so can't do site visits easily. Trying to figure out if pre-launch offers are actually better deals or just marketing for places like Balaji Group or Galaxy Group. For a 3BHK around ₹80L, are builders giving real spot discounts or is their "no-price-drop" policy actually true? It's tough to gauge from here. Should I jump on pre-launch or wait for ready possession for better negotiation? What's your experience getting actual price leverage in Rajkot?
