Its too new a cpu for such things to happen. I personally ordered a 12400F when it launched for 12k from flipkart and received a genuine chip. Everyone else was selling it for 16-17k.Far too frequent for me, if I go by such instances with Retailnet in this thread only.
Flipkart dealsSaw on FB today, some guy ordered 5800x3d from FK , got some intel proccy in amd ryzen box. Seller was retailnet That was me. Never flipkart again.techenclave.com
Great deal though if folks get the genuine item but definitely tread carefully, really carefully.
Most of this nonsense is done either by buyers who returned the cpu or delivery agents.
