So I did a mock drill. I attempted to purchase Mi TV on Flipkart on 29th flash sale. I was able to add it to cart. Also, it took 5-10 min for them to go out of stock. Which means I could have bought an Mi TV easily.
On weekend though, I was able to get my old TV repaired. So buying a new TV is deferred for a while.
Thanks for everyone to participate in this discussion.
