I usually prefer to shop online and most of the time I will get my packages delivered through Blue Dart couriers services.i have been getting parcel from blue dart from last 4-5 years, they provide good service.The website provides proper tracking and gives the delivery date and delivery done within date specified.i got no issues with Blue dart courier till date.
The customer care service is also available and will assist in case there is any delay in delivery or any other issues but fortunate no problem till now. I can say for sure Blue Dart is one Top Couriers in India.
