Mi store is one of the most using sites in today's day to day life . Some people think that their flash sale is just fake or something else. But personally let me tell guys something I bought many products from these site ( mi Redmi note 3, Redmi 3s , mi band , charger cable etc ) they never delivered any damage stuff's or faulty items. And they have one of the best delivery duration they deliver all the products within 2-3 days which is very fast . Some people do think they don't sell many product because it's always out of stock but guys it's their way of selling product to get curious about their product always.
