DTDC

They provide the cheapest courier service from Singapore to India. My Courier was delivered safely and earlier than the expected delivery date. Go an hour earlier atleast. If you have patience to deal with them, and not in a hurry and save money, you can consider this option.

Friendly and Delivered on time!! Was using them to send documents back and forth between India and Singapore.

Had a good overall experience. My stuff was delivered in India on time.
