Flipkart is good shopping website. I have purchased many items from flipkart and had good experience of delivery and customer support.
But most irritating thing is that flipkart forces to use mobile application. I like to use PC but for all products it has offers if the order is placed through mobile application.
Flipkart also shows fluctuating prices which is also irritating. I purchased Moto X play and suddenly price dropped by Rs 1500.
