Flipcart if you are comparing with myntra or other online shopping sites in regard of its delivery and return services, it is more efficient. First of all I have experienced this myslef while returning a product flipcart has ecart which takes around 1 to 2 days max in getting a person to return the product and the most benificial thing about it is that you will get your refund be it in your bank account or in your flipcart account on the day itself. Most of the times the product will reach before the prescheduled time. So you dont have to worry about that as well. In terms of product originality as well its more or less accurate than other eshopping sites as well.
