Flipkart noone is going to beat them at Delivery!!. Review on Flipkart

I have ordered a few products during big billion day sale. It is said that the product will be delivered in 5 to 7 days due to high demand, but I ordered it . Next day got message from them that your order has been packed and shipped. Next day around 10 o clk I received the order and paid them via card!

That's first instance. And after few days there was 80 percent offer for buying 3 or more cloths from them. I ordered abt 5 tshirts and billed only 20% . I thought this time they would take time to deliver and thought we wont be given priority. Next day one of the t shirt was delivered . And after two days remaining shirts got delivered. I even tracked all the products from their app and it was perfectly updated. But when we order in some other ecom sites they dont care much abt delivering product on time. Only drawback inflipkart is they are forcing user to use their app instead of website which makes us little uncomfortable, all offers are only on app!
