Post office insurance is such a joke. By way of example, I've had overnight shipments delivered three weeks late and wanted the $20 back for the shipping cost. You go to the store, they tell you they can't process refunds there and you have to do it online. You go online, and the claim system would tell you to do it in the store. Never got one refunded, ever.

It has to be a friggen nightmare to get them to pay when you do lose something (like those grips). I'm sure it's all telephone runaround and deferring blame, probably costs $600 worth of work to get a $300 insurance payment.
