What is the least expensive way to ship to India from the U.S.?

[purveenshah]

What’s really the cheapest way to ship something from the U.S. to India? I’ve heard options like USPS flat-rate boxes, courier services, or even freight forwarding, but the prices seem to vary a lot depending on size, weight, and customs. Some people say USPS is affordable but slow, while others suggest smaller shipping companies that claim to offer discounts. Has anyone here actually found a reliable low-cost option that doesn’t end up with surprise fees when it reaches India?
