POCO F1 Next Sale Date?

According to my knowledge, POCO F1 has been launched already. So please can you tell me about POCO F1 1st Flash date? So that I can book this mobile. Just explain every detail about this phone including POCO F1 next sale date. Also, if you can help me with the best chrome extension for POCO F1 flash sale on Flipkart and MI. Is there any auto-buy chrome extension which works for both Flipkart and MI? Explain the sale timing, sale date, etc. with other details. Is this flash sale for POCO F1 is daily or weekly? Because if I miss the first sale when can I try again for the POCO F1. So please tell POCO F1 next sale date with all other details. Thanks in advance..!!
