It depends on where you sending it and to whom. I always pay up for global priority insured because on other occasions it goes missing.
If you know about the postal system in India you on occasion have to "tip" the mail man if you want your mail and with global prioriority there is none of that. If you are mailing to Delhi you have a good chance of it getting there , same with Calcutta. Bombay less so and Patna you better send an armored car.
Also be vague on the shipping label if you don't send it Global because on occasion this could be a shopping trip.
