Yes, quite a few items this past year or so. No issues with any so far. Most items have been books, ps3 games or supplements in the 500 to 3k range, so nothing past 5k yet. Not too sure about insurance, but companies like DHL/BlueDart should have something I guess.
Shipping charges have ranged from free to Rs 50/ Rs 100 (for local items) to Rs 500/ Rs 750 (for US shipments). Shipment times range from a couple of days to about a month depending on if you're paying anything for it.
