Give me an education about this "PIRATE SHIP" method that has been discussed here.

So 100.00 is the max amount on insurance.

NO!!!
You can insure it for any amount you wish (I've gone up to $2200). You just need to specify how much insurance coverage you want and pay the nominal extra amount.
UPS includes $100 in insurance with every shipment; last I knew, the USPS only includes $50 with Priority Mail.
Look under Extra Services and check the box. There you can fill in the amount you wish.
