Flipkart. Its a good app I have done lot of shoping through this app and the product was also good but one day when I ordered shoe for my mom it took more then 12 days to deliver not only that the size of the shoe was not matched one was larger then another, because of that my mom had to wear old sandle while going for holidays, my mom was very dissapointed. Then we decided to return but it took more then 18 days to give refund in my wallet. So I think flipkart doesn’t provide good service. But overall its a good app. I still use it
